Chennai: A 39-year-old 'devotee' who threw a petrol bomb at a temple in Chennai on Friday has been arrested, the police said, adding that no one was injured and nothing was damaged.

The man, later identified as J Murali Krishnan, was "heavily drunk" when he threw the petrol bomb, police said. He was immediately overpowered and taken into custody, they added.

A local resident who lives under Kothawal Chavadi police station limits, Krishnan, who is a devotee of the temple, said he committed the offence as he was "frustrated" that the deity did not "answer his prayers", according to the police.
