The rock group Babyshambles has cancelled a gig in Norwich on Sunday night after the arrest of lead singer Pete Doherty.
Babyshambles frontman Doherty is being held by Shropshire Police
It is understood Doherty was arrested on suspicion of the possession of class A drugs in Shrewsbury, Shropshire.
Doherty's band Babyshambles had been due to play at a sell-out gig at the University of East Anglia (UEA).
A spokesman said the gig would either be rescheduled or the 1,500 ticket-holders refunded.
A West Mercia Police spokesman said two people arrested were expected to be interviewed on Sunday afternoon.
Doherty is the boyfriend of the supermodel Kate Moss.
