Man shot outside Birmingham's Rainbow Warehouse nightclub 11 August 2013 Last updated at 13:55 A man has suffered life-threatening injuries in a shooting outside a Birmingham nightclub. The 35-year-old was shot in the abdomen outside the Rainbow Warehouse in Digbeth's High Street at about 23:45 BST on Saturday. Police said they believed it had been a targeted attack and the gunman escaped on foot. Roads in the surrounding area remain shut and forensic teams are still at the venue. The victim was given first aid at the scene and taken to hospital where he remains in a critical condition, according to West Midlands Police. Officers said the man's family had been informed. Motive 'unclear' The venue had been hosting a two-day festival called Circoloco, described on its website as "featuring house and techno sets." Carole Foster BBC Midlands Today reporter I'm standing in front of a Victorian pub which is within the police cordon. The area is busy during the day but even busier at night, and there must have been many people around when this man was shot. From what I can gather from police it must have been a very frightening experience for clubbers. Police officers have been here through the night, searching for any forensic clues. People who live nearby say it is increasingly becoming a difficult place, with residents worried that it is becoming rough. The roads have been closed off and the police expect to be here for some time. Det Insp Justin Spanner said the shooting "must have been very frightening for clubbers to witness" but the motive was unclear. He urged anyone who had been in the area at the time to contact police. "We've been working hard to reduce gun crime across the region but crimes like this - no matter how rare they are - tarnish Birmingham's reputation as a great place to enjoy a fantastic night out," he added. Adderley Street and surrounding roads are closed while searches are carried out by specialist officers. The force said it expected the roads to remain closed "for some time" and urged drivers and pedestrians to avoid the area. Amy Robbins, who works in a shop next to the venue, said: "At the moment there are police vans everywhere and a large cordon outside. They're not letting anyone past and we haven't been told anything about what's going on. She said the venue usually held weekly events but that Circoloco was its biggest event of the year. The Circoloco club night plays in numerous venues around the world, including in Australia and Ibiza. Ms Robbins said the venue had rented out a large car park under some arches for the event. The second day of Circoloco has been cancelled. Police urged anyone with tickets to contact the venue or organisers for information.
