The Isis nightclub.
A 26-year-old man suffered stab wounds after an incident outside Isis at about 3.55am yesterday.

A cordon remains around the nightclub and its car park in Redfield Way, Lenton Industrial Estate, Dunkirk, while forensic officers examine the scene.
Police believe other people may have been injured in the incident.
A woman who was at the nightclub, and did not want to be named, said: "It was about 3.50am and there was lots of fighting.
"I saw people stamping on people's heads, then the police came and everyone was outside.
"Taxis weren't coming to the club and there was just loads of people left outside."
The car park opposite Isis, which is surrounded by Chiquito, Nandos and Frankie and Bennys was closed until about 1pm.
Isis' owners said they could not comment on the incident.
