Chaos erupted, chairs were tossed, broken and posters destroyed by thousands of Metallica fans in India after the band cancelled their first ever show in New Delhi due to technical difficulties. 

Police arrested 4 people from the company responsible for booking the band after cheating many people who had waited hours for Metallica to perform Friday night.

Metallica promises to refund all who had bought tickets.  The concert was a buildup  to Sunday's Grand Prix Formula One Race in New Delhi.

The band still plans to perform in the Indian city of Bangalore on Sunday.
