Investigation into Tuesday evening's serial bomb blasts in Mumbai's suburban trains will also consider whether they have any connection with separate two violent incidents in the state in the last one week, Maharashtra Chief Minister Vilasrao Deshmukh said.

He was replying to a query after being asked if last week's incidents at Bhiwandi, where violent protestors opposed construction of a police station adjacent to a mosque, and Dadar had any connection with today's serial blasts.

Two policemen were killed by a violent mob in Bhiwandi town of neighbouring Thane district in the backdrop of killing of two protestors in police firing last week.

On Sunday, Shiv Sainiks went on a rampage in Dadar after unidentified persons desecrated bust of Shiv Sena chief Bal Thackeray's late wife Meenatai at Shivaji Park.
