The Hyderabad Police has made elaborate security arrangements for the Friday prayers at Mecca Masjid, in the wake of the bomb blast and subsequent police firing incidents last Friday in which 14 people were killed and over 50 were injured.
The City police also made security arrangements at the other major mosques in the city. The police also installed closed circuit TV cameras at vantage points in Mecca Masjid so that the police could observe the movement of any person from outside. Door Frame Metal Detectors have also been placed at the entrances to the mosque and the police also decided to deploy personnel with handheld metal detectors also to provide strict security at the Masjid.
Mobile phones will not be allowed to be taken inside Mecca Masjid. Those carrying mobile phones will have to deposit them at the gate. This is the first time that mobile phones are not to be allowed inside the Masjid. "We are getting good cooperation from the people and hope that the Friday prayers will pass off peacefully," Hyderabad City Police Commissioner Balwinder Singh told media persons after a high-level review meeting on Thursday.
Minority Welfare Minister Mohammed Ali Shabbir reviewed the long-term security measures at Mecca Masjid and four other major and historic mosques and the Haj House in the city. It was decided to have permanent security system in place at these mosques.
"We will explain to Muslim religious and political leaders that the situation has now changed and they should cooperate with the government for the safety of worshippers," Shabbir said.
The review meeting was attended by the Police Commissioner, Hyderabad District Collector R V Chandravadan, and senior officials of State Archaeology and Minority Welfare Departments. The minister said it was decided that six door-frame metal detectors and five hand-held metal detectors would be deployed permanently at the three entrances of Mecca Masjid. It was also decided to install three dragon lights and 21 CCTV cameras, with a facility of 30 days' recording, at different points inside the Masjid. A control room would be set up outside the Masjid.
The Minority Welfare and State Archaeology Departments, which are responsible for the upkeep of the mosque, would oversee the implementation of the security measures. The security equipment is estimated to cost Rs 30 lakh. In all, 24 people would be recruited to handle the security gadgets and CCTVs at the Masjid.
The CCTVs would help in monitoring the movements of visitors, including worshippers and tourists to the Masjid. A cloakroom would be opened near the entrance where all visitors would be required to deposit their belongings before entering the Masjid.
Since last Friday's bomb blast was triggered with a mobile phone, the city police are also contemplating installing jammers in the Masjid to jam mobile signals in the area.
The Archaeology Department and the AP State Wakf Board will also install metal detectors and other security equipment at Royal Mosque in the public gardens adjacent to the state legislative assembly complex, and Mallepally, Khairatabad and Toli mosques. The police commissioner said that the police were making progress in the investigation of Mecca Masjid blast and added that 'we have sent our teams wherever we felt necessary.' The Special Investigation Unit probing the blast has recorded the statements of eyewitnesses, injured people and mosque workers.

Churches installing cell phone jammers

MONTERREY, Mexico - It was the reporters who noticed first. Unable to call their editors while covering the weddings of the rich and famous, they asked the priest why their cell phones never worked at Sacred Heart. His reply: Israeli counterintelligence.
In four Monterrey churches, Israeli-made cell phone jammers the size of paperbacks have been tucked unobtrusively among paintings of the Madonna and statues of the saints.
The jarring polychromatic din of ringing cell phones is increasingly being thwarted — from religious sanctuaries to India's parliament to Tokyo theaters and commuter trains — by devices originally developed to help security forces avert eavesdropping and thwart phone-triggered bombings.

The Indian parliament had jammers installed after politicians ignored requests to turn off their cell phones and legislative sessions were constantly interrupted.
In Italy, universities started using the blockers after discovering that cell phone-savvy teenagers were cheating on exams by sending text messages or taking pictures of tests.
The four Roman Catholic Churches in this northern city began using the devices, from Tel Aviv-based Netline Communications Technologies Ltd., after an insurance salesman imported them as a personal favor for a priest.
"There are still many people who don't understand that being at Mass is sharing a moment with God," said the Rev. Juan Jose Martinez, a spokesman for archdiocese. "Sadly, we had no other choice but to use these little gadgets."
Purchased for about $2,000 each, they can be turned on by remote control and emit low-level radio frequencies that thwart cell phone signals within a 50-100-foot radius.
Users get a "no service" or "signal not available" message on their cell phones.
Laws vary
Although Mexico has no law against the devices, the private use of cell phone blockers is illegal in the United States and most Western countries. But the tide is turning.
Japan allows public places such as theaters and concert halls to install jammers, provided they obtain a government-issued license. And last week, France's industry minister approved a decision to let cinemas, concert halls and theaters install them — as long as provisions are in place so emergency calls can still be made.
In Scotland, businessman Ronnie McGuire, owner of Electron Electrical Engineering Services, imported Taiwan-made cell phone blockers and sold them to hotels, restaurants and bars until a local newspaper reported his activities, which were illegal in Britain.
McGuire has said he will still import the Taiwanese devices but sell them for export only to countries where they are allowed.
Loreen Haim, the director of marketing and sales for Netline, wouldn't say how many devices the company sells per year or what country buys the most.
In Mexico, the main clients have been banks looking to stop would-be robbers from communicating with their accomplices and the Mexican government, which is planning to use them at prisons, Haim said.
Wedding bells
In Monterrey, the Sacred Heart church, a baroque temple favored by Mexico's elite for weddings, church officials acquired their blockers two years ago.
"Whenever there was a wedding, cell phones would ring every five minutes," said Bulmaro Carranza, a parish clerk. "It was a real problem because there were times when even the groom would forget to turn his cell phone off."
For months, the devices went unnoticed until reporters covering the weddings began complaining that their cell phones never worked.
Since word of the jammers went public, priests from around Mexico have been calling to find out how to get them, said Carranza.
At Sacred Heart, a device at the entrance to the church and another by the altar are turned on right before every Mass. Still, priests remind parishioners to turn off their phones before beginning the services, hoping good cell phone etiquette will eventually catch on.
The other Monterrey churches with the devices — The Rosario, San Juan Bosco and Our Lady Queen of the Angels — are also frequented by wealthier parishioners, Martinez said.
"For a lot of them, the cell phone is a necessity. But that shouldn't prevent them from having good manners and remembering that one must respect sacred places," Martinez said.
Margarita Escobedo, a Catholic who goes to church at least twice a week and volunteers at the San Genaro church, says she would welcome the jammers in her parish, where cell phones are becoming a nuisance.
"Those who bring cell phones to church are not committed to God," Escobedo said. "It's very distracting to be praying and suddenly hear birds chirping or techno music."
