NEW DELHI - Thousands of disappointed fans have broken chairs and torn posters after organizers cancelled a Metallica concert on the outskirts of the Indian capital.

The Press Trust of India news agency says police arrested four people from the company that had organized the concert on charges of cheating people who had waited for hours for the scheduled Friday performance by the American heavy metal band.

Organizers said the concert was called off due to technical difficulties.

Metallica promised full refunds to those who had bought tickets.

The concert was part of the buildup to Sunday's Indian Grand Prix Formula One race in New Delhi.

Metallica is scheduled to perform in the southern Indian city of Bangalore on Sunday.
