A Kolkata Police constable, who was beaten up severely by unidentified men on Holi at Birati in the city's northern outskirts, today succumbed to his injuries.

Though the police quoting an initial complaint made with the local police station said that a property dispute was the reason of the assault on constable Ashim Dam, the victim's family alleged he had been lynched because he protested against eve-teasing.

Commissioner of Salt Lake Police, Rajeev Kumar said, "Investigation is going on with the local police going through the details of the complaint by Dam's family."

He said that a person had already been detained and is being interrogated in connection with the incident which took place at Kishore Para near the NSC Bose International Airport.

Assistant Deputy Commissioner (ADC) Salt Lake Police Tarun Haldar earlier said that 27-year-old Dam, attached with the Entally police station, and two other persons were injured in a clash over property dispute in the area on that day.

Haldar said Dam and the two others were admitted to a hospital where Dam succumbed to his injures today.

Expressing concern over the incident, Minister of State for Health, Chandrima Bhattacharjee alleged that CPI(M) goons had taken revenge over the Trinamool Congress leaning family.

Bhattacharjee said she had asked the police to arrest the culprits immediately.
