TMC minister Sidduqullah Chowdhury’s convoy was allegedly attacked by his party supporters during his visit to his Assembly constituency, Manteswar, on Thursday.

According to sources, the protesters carrying black flags vandalised his car and called him “thief”, “extortionist”.

“This was an attempt to kill me,” said Chowdhury as he threatened to quit the TMC. He also called a protest march on July 10.

“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 a corrupt TMC panchayat leader. The local police witnessed everything but took no action. I have contacted senior officials,” Chowdhury said.

“If this continues, I will have to quit the party,” he added.

He accused local TMC leader Zila Parishad member Azizul Haque of being behind the attack.

Haque, however, denied the charge.

TMC leader and chief of Monteswar gram panchayat, Rafiqul Islam Sheikh, said that the locals had expressed their anger against Chowdhury. “Chowdhury is a corrupt leader. He extorts money. He never visited Monteswar after winning the election. Local people are angry with him. This was a spontaneous outburst,” Sheikh said.
