A St Xavier’s College teacher has alleged that acquaintances of his neighbour thrashed him, his wife and two children after an argument over parking of vehicles in their New Town cooperative housing society.

Ankur Roy, the head of the chemistry department at St Xavier’s College, lodged a complaint with New Town police station on the night of November 17 against a teacher of a Barrackpore college.

Roy alleged that relatives of the teacher were involved in the attack on him and his family earlier in the evening.

An officer of the Bidhannagar commissionerate said police had started investigating the matter.

“We are trying to get the CCTV footage… we will speak to the neighbours,” the officer said.

Another officer said Roy and the other teacher had been embroiled in arguments over parking their vehicles for the past few years.

“There is an ongoing case at the Barasat court over their parking dispute. We are investigating from every angle,” the officer said.

In his complaint, Roy has said that he returned home with his wife, son and daughter after a medical check-up and parked his car at “the usual spot in the parking lot of his AL Block flat”. After parking the vehicle as his wife and children began walking towards the lift, at least five men attacked them with iron pipes, he has said in the complaint.

“I heard my wife and children scream... as I went towards the lift lobby the men attacked me,” Roy said.

“The blows left my wife with a broken arm; I, too, received multiple injuries.”

The men fled as neighbours came to their rescue.

Roy’s neighbours took him to the Salt Lake Sub-divisional Hospital where he was given first aid, after which he and his family went to a private hospital off the Bypass.
