Illegal rave in Norwich shut down after complaints
Police were called to shut down an illegal rave in Norwich after complaints from nearby residents.
A large crowd of more than 150 people gathered under the A146 flyover off a field in White Horse Lane in Trowse just after midnight.
Members of the public complained to police about amplified music, which was switched off at about 09:15 GMT.
One person was arrested on suspicion of possession of drugs, a Norfolk police spokesman said.
Supt Mike Fawcett said: "It has been an exceptionally challenging night for police resources across the county and we have had to take this into account in assessing our response to this event, as well as work within the powers granted to police under current legislation.
"Officers have been working throughout the night to identify key participants and negotiate to bring this illegal event to an end as quickly and safely as possible for all concerned.
"We acknowledge that local residents have been disturbed by the amplified music and we will seek to take further action against those involved."
