The police officers investigating the Rs15.20-lakh burglary at the Dadar (West) branch of Union Bank of India on Friday were confounded by a four-digit number scribbled on a wall. But the confusion gave way to shock when they realised that it was the code for the burglar alarm installed outside the bank’s strongroom.
“We were trying to investigate why the alarm did not go off. We found that the alarm had two different modes used for working hours and post-working hours,” said an officer on condition of anonymity.
“During the working hours, the alarm was in kept in day mode wherein only the original key or the master key could be used to open the strongroom. Once the bank was closed, one of the employees would punch in a code that would activate the night mode. In this mode, the alarm would go off even if someone used the original key to enter the strongroom. The idea was that there was no need for anyone to be there after office hours,” the officer explained.
However, the alarm did not go off as the four-digit code used to change the mode was scribbled on the wall right next to the alarm. “The CCTV footage shows that the accused saw the number on the wall and used it to change the alarm mode. He then went to the cashier room, took the key and opened the strongroom door,” the officer said, adding that the code had been written on the wall for the past six months.
S Unawne, senior inspector, Shivaji Park police station, confirmed the news, saying, “We are investigating the case. No arrests have been made in the case so far.”
The police have, however, not been able to identify the accused from the CCTV footage as he was wearing a helmet. The police suspect some insider help in the crime.
Despite several attempts, the Union Bank of India was not available for comment.
