The police nabbed two men, who were part of a three-member gang which attacked a head constable. The policeman was attacked when he questioned the gang for suspiciously wandering on the streets of Shankar Nagar near Pallavaram on Thursday night.
Pauldurai is said to have called them to the police station for an inquiry when the trio assaulted him and escaped from the spot. A few passers-by, who noticed the incident, chased and overpowered two men, who were later arrested.
