According to Senior Police Inspector of the Borivali GRP Shyam Gaikwad, the control room received a call at 7.40 pm, the scheduled time of departure of the Ahmedabad-bound train from Bandra Terminus to Ahmedabad. Prajapati, who works at a property brokerage firm, was to board the train from Bandra Terminus but had missed it by minutes.

“He then called the city control room saying there was a bomb on board. He did that to delay the train’s departure from Borivali station so that he could still board it from there,” said Gaikwad. Instead, the train was stopped at Andheri station and checked thoroughly for nearly two hours. Nothing suspicious was found on board and the train finally left at 9.50 pm.

However, the city control room telephone lines had a caller identification system installed and his cellphone number was recorded. At 10.30 pm, as Prajapati boarded the train comfortably at Borivali and took a seat in the general coach, he found his phone ringing. When he answered the call, he was immediately nabbed by policemen on board.

“We knew he will be at Borivali station waiting to get into the train,” said Gaikwad.
