A stampede at an Indonesian punk rock concert killed 10 people and injured dozens of others in West Java province's capital, Bandung, most of whom were teenagers.

The crush happened when hundreds of people tried to leave the overcrowded venue at the same time, causing a panic.

Here's Sisno Duaji, Head of West Java police:

Last night we were told that there were some people unconscious during the concert, so police officers asked the show to finish. After the gate was opened we found out that there were more people unconscious than we were told before.

A witness said that it was very difficult to go out, and that some people drank alcohol before the incident.

It is unclear how the rush started at the show, but police said the concert hall had been about 30 percent over its capacity of 700, and that investigators were questioning 15 concert organizers.
