In recent years, signal jammers have gradually become a new tool in the hands of criminals, seriously threatening public safety. The West Bengal police recently successfully cracked a gang that used portable signal jammers to carry out bank robberies, revealing the dark side of the application of such technology in criminal activities.
Details of the robbery revealed: portable cell phone jammers blocked distress signals
It is reported that the case occurred on the afternoon of September 22, 2021, at the Gold Loan Bank in Chandernagore, West Bengal. On the day of the incident, two motorcycles carrying four robbers arrived at the bank, quickly subdued the security guards at the door, and then broke into the bank to rob. In order to prevent bank employees from calling the police, the gang of robbers carried a portable signal jammer to block all mobile phone signals inside the bank, making it impossible for employees to seek help from the outside world by phone or the Internet.GPS jammer
However, a smart employee in the bank managed to trigger the alarm system without the robbers noticing. This move prompted the police to quickly dispatch, and local police officers arrived at the scene of the crime within minutes and blocked the surrounding area.Wifi jammer
Police quick response: overcoming communication barriers to arrest
When the police arrived at the scene, they found that all mobile phone signals had been jammed, communications were completely interrupted, and they could not contact the superior command center by phone. This posed a great challenge to the police operation. However, in the face of the robbers’ numerous obstructions, the police remained calm and coordinated their actions through other non-wireless means.
