NEW DELHI (AP) -- An electricity generator blew up Saturday outside a cricket stadium in southern India shortly before a match was about to start, police said, injuring two people and setting off panic among fans.

The Chinnaswamy Stadium in Bangalore is hosting a game between the home team, Bangalore Royal Challengers, and the Mumbai Indians, as part of the popular Indian Premier League tournament.

A police official at the city's police control room, who requested anonymity because he was not allowed to speak to reporters, says initial reports do not indicate that there was any foul play behind the explosion.

The sound of the blast, which took place as thousands of spectators were entering the stadium, sent nervous crowds running in panic.

Shankar Bidari, the city's top police official, tells reporters that the match will continue though it might be delayed.

Sports venues in India have faced tight security amid fears that Islamist radical groups may target them.
