Police and Coast Guard have started probe after an unidentified boat was found stranded off Vasai coast in Maharashtra's Palghar district, officials said.

  

The boat -- a mini barge -- was spotted around 10 nautical miles from Builgaon-Kalamb area. It raised red flags as usually fishing boats do not venture in this rocky patch, said a local police official. 

A small surveillance aircraft was also sent to inspect it but it didn't get a clear view due to bad weather, he said.

 

Two persons were also seen on board the boat, the police official said, adding that probe was on. -- PTI
