Maharashtra Police has sounded an alert after Intelligence Bureau informed them about terror threat to the state, Director General of Police S S Virk said in Mumbai on Tuesday.

"Intelligence Bureau has given a fresh alert about the threat, two to three days back. I had instructed my men to be alert," Virk said.

Virk, however, did not give details of the threat mentioned by IB.
