The Chennai City Police nabbed one person and are searching for two more who attempted a burglary at gun-point in Triplicane on Sunday.
The accused was identified as Ravikant Singh. He and his accomplices from Bihar and were targeting pawn brokers, sources said.
A senior police officer said Munilal was a pawn broker and his shop was in the ground floor of his house on Jani Jhan Khan Street near Ice House.
On Sunday morning, three burglars entered his house. When the domestic help tried to raise an alarm, one of the burglars drew a gun and threatened her not to shout.
A neighbour who was passing by heard her shout and tried to enter the house. On seeing this, the three burglars tried to escape but one of them was nabbed by the public.
Preliminary investigation revealed that the three persons were natives of Bihar and had taken a room in Royapettah to rob rich persons in the locality based on inputs from their contacts in the city.
