Three youths on a bike tried to pull down a woman from a bike on BT Road early on Monday and thrashed her brothers before a passing police patrol came to their rescue, police said.

Cops managed to arrest one of the youths on the spot while the other two fled.

The woman was returning to her in-laws’ place in Khardah after participating in the immersion proceedings of the Lakshmi idol at her parents’ home in Sovabazar when the youths attacked her around 1am near Kamarhati, the police said.

The woman was riding pillion on her brother’s bike. Her other brother and sister were accompanying them in another bike, an officer of Khardah police station said.

“The woman has claimed in her complaint that three youths who were not wearing helmets started following them on a motorcycle soon after they had crossed the Kamarhati junction on BT Road,” the officer said.

“The youths started trailing them before overtaking them and calling her names and making indecent gestures.”

After some distance, near the Alpine Dairy on BT Road, the youths suddenly stopped in front of the bike she was on with one of her brothers. They apparently tried to pull her down from the seat and hurled abuses at her.

Her other brother and sister who were on another bike came to their rescue. The woman has told the police that one of the youths flashed a knife when her two brothers tried to stop them. They thrashed her brothers, she has said in her complaint with Khardah police station.

Around the same time a Khardah police patrol was passing by. The team, alerted by the woman and her sister’s cries for help, stopped. Officers managed to arrest one of the three youths. He was later identified as Mohammad Selim, the police said.

A search is on for the other two youths, an officer said.
