Police on Wednesday released a sketch of a person suspected to be involved in the twin blasts outside Bangalore's Chinnaswamy Stadium on Saturday.
17 people were injured in the blast which delayed the start of the IPL match between home team Royal Challengers Bangalore and Mumbai Indians by an hour.
There were two blasts, one near the stadium's gate number 12 and another outside the stadium, and a third crude bomb was found on the roof of a ticket counter at gate number 8 when the three-hour match was in progress and about 40,000 fans were inside the flood-lit stadium.
The police also recovered two crude bombs near VIP gate number 1 and on the pole of a billboard near gate number 9 on Sunday during the combing operations that were carried out to sanitise the stadium in run-up to the scheduled semi finals April 21-22.
After the blast, the two semi-finals of the Indian Premier League-III T20 tournament were shifted to Mumbai from this tech hub.
