Over a 100-strong mob attacked a man and thrashed him badly, suspecting him to be involved in slaughtering a cow, whose carcass was found near his house in a village in Giridih district, the police said.
The mob raided the house of the man at Barieya village last night shortly after finding the carcass of the cow, the police officials said.
The man was rescued by police from the marauding mob and admitted him to a local hospital, but was later shifted to another hospital in Dhanbad owing to the seriousness of his injuries, they said.
