The West Bengal Police arrested five people for attacking state minister Siddiqullah Chowdhury’s convoy after Chief Minister Mamata Banerjee expressed her disappointment over the incident.

Reacting to the development, Bengal Urban Development and Municipal Affairs Minister Firhad Hakim told The Indian Express on Saturday, “The chief minister became unhappy and expressed her anger when she heard about this (convoy attack). She ordered the police to take stern action.”

On Thursday, a section of Trinamool Congress (TMC) supporters pelted stones at the convoy of Bengal Mass Education Minister Chowdhury in his Assembly constituency, Monteswar, under East Burdwan district. Chowdhury was also heckled with slogans calling him ‘thief’, ‘extortionist’, and shown black flags, brooms, and shoes.

“Stones were pelted at my car and other vehicles in my convoy. The windshields were smashed. This was an attempt to kill me. The attack was planned by TMC Zila Parishad member Azizul Hoque. The local police witnessed everything but took no action. I have contacted senior officials,” Chowdhury said, and added, “If this continues, I will have to think of quitting this party.”

The TMC minister has called for a protest march in Kolkata on July 10 to condemn the incident.
