Five people fought for their lives on Sunday, a day after a grenade attack killed two concert-goers and wounded 17 at a show featuring Bollywood star Shar Rukh Khan and other top Indian film actors here, the police said.
Shar Rukh, who apparently didn't immediately realise what had happened and continued his performance until security staff whisked him off-stage,rushed back to Mumbai on Sunday after the security guards drove his entourage straight to the airport, hours ahead of their planned departure.
None of the artistes were hurt, but former Indian cricketer Ravi Shastri's wife was wounded and admitted to hospital.
There was no immediate claim of responsibility for the attack and no one has been arrested so far.
The grenade attack came just hours after the police used tear gas to break up a protest by Buddhists who tried to prevent the concert---held a day before the anniversary of the death of a leading Buddhist cleric.
Demonstrators said they wanted only religious activities over the weekend.
The monks called off their protest several hours before the show started after Shar Rukh Khan apologised for the inadvertent timing of the concert, but supporters of the monks later attacked cars and concert-goers and clashed with police who retaliated with rubber bullets.
The Indian government condemned the "terrorist incident" and said New Delhi awaited results of the Sri Lankan investigation into the attack.
