Calcutta police anti-rowdy squad seized 51 crude bombs from a spot a stone’s throw from the BJP election office in Hastings on Saturday night after receiving military intelligence inputs.

The bombs were stashed in a bag and left along the roadside near Kidderpore crossing.

A senior police officer said they were in the process of analysing CCTV footage to ascertain who left the bombs.

“This is a serious matter and we are taking it up on a priority basis. CCTV footage is being scanned,” said the officer. No one was arrested in connection with the case till Sunday evening.

State BJP unit chief Dilip Ghosh asked why it had to be the job of the (Centre’s) military intelligence to know about the bombs, his statement taking a dig at state police.

He alleged it was part of a larger conspiracy to attack his party. He said had the bombs been used on the party office or workers and leaders, it could have been “disastrous”.

“Everyone has seen, and is aware of the extent of violence being unleashed on the BJP in Bengal since the election results were announced. Mamata Banerjee has been claiming that since she took oath, it has stopped. But it is far from the truth,” said Ghosh.

“This is proof, once again, that only one industry thrives in Mamata Banerjee’s Bengal, that of crude bomb-making,” added the Midnapore MP.
