Broken barricades, torn posters, strewn equipment and angry youngsters - excitement turned into aggression at the Leisure Valley Ground here, as American heavy metal band Metallica's performance was Friday postponed to Saturday following "technical faults". Police have launched an inquiry into the incident.

The Metallica concert, the opener for the 'F1 Rocks' series of performances for the upcoming Formula 1 event, was set and the audience was kicked about head-banging to the high-voltage music, until the spoiler came. "F1 Rocks and Metallica regret to announce that due to technical difficulties, the Metallica show at Gurgaon has been postponed until Saturday. We apologize for any inconvenience caused," said an official statement from the organisers, DNA Networks.
