A group of relatives and some locals gathered at the spot and allegedly assaulted Das, who later succumbed to injuries.
A migrant labourer was beaten to death by a mob in Thiruvallur district after he allegedly misbehaved with a woman, police said on Saturday.
The victim has been identified as Prosenjit Das (35), who along with six labourers from Assam came to Thiruvallur in search of a job and were staying in a rented room, they said.
Initial probe revealed that Das, who was under the influence of alcohol, misbehaved with a woman under the pretext of asking for drinking water at her residence. However, the woman was forced to shut the door and go inside her house for safety.
