A man in his early thirties was found dead hanging from the handrail of stairs at a shopping complex in Perumbavoor.
The police are yet to identify the deceased person, suspected to be a migrant labourer.
Preliminary examination showed the body had several injury marks on it, raising suspicions of a murder. The police said the deceased person had been engaged in a drunken brawl with a few of his friends the other night, which might have led to the murder.
