  Introduction of mobile phone jammers

  In order to deal with the problem of mobile phone abuse in prisons, prison authorities have begun to introduce mobile phone jammers. These devices block prisoners from contacting the outside world by transmitting interference signals, making mobile phones in the prison area unable to work normally. Director General of Prisons Sandeep Goel said last month that part of his goal was to stop the use of mobile phones in jails, which was a major concern for the Delhi Police.
