The snatched gold chain was recovered from one of the suspect while his accomplice managed to escape from the spot, a police official said today.
The incident took place on Wednesday when one Ram Swaroop Sharma, a businessman who lives in C-Block of west Delhi's Janakpuri area along with his family, was walking toward the nearby market with his wife Ritu around 9 PM.
"As Sharma was walking ahead of his wife suddenly heard her cry for help. As he turned back, he saw two men on a bike fleeing after snatching his wife's chain. He then chased the motorcycle for a few metres and pulled down the pillion rider," said a police official.
The accused was identified as Rajkumar Kohli and the chain was recovered from him.
"The accused has been arrested and a case has been registered against him. His associate has been identified and efforts are on to arrest him," he added.
