Several police guards were injured in a low-intensity explosion outside a southern Indian stadium barely minutes ahead of a star-studded cricket match Saturday, authorities said.

The explosives placed near one of the gates of the packed Chinnaswamy Stadium in Bangalore went off at about 3:15 p.m. (5:45 a.m. ET), city police commissioner Shankar Bidari told reporters.

"There's no cause of panic," he said.

At least five police personnel guarding the stadium suffered minor injuries in the explosion, which authorities said was not powerful. The blast, however, delayed the match for almost an hour.

Some of the world's star international players are participating in the Indian Premier League (IPL) tournament, which is due to wrap up on April 25.

Indian authorities insisted that the event is under tight security.

Saturday's blast in Bangalore, India's tech hub, was the second in the country since a deadly explosion in the western city of Pune in February killed more than a dozen people.
