Four people have been arrested after a wine bar doorman was stabbed with a machete.
Sussex Police were called to the Mixologist Wine Bar in Church Road, Hove, at about 23:20 GMT on Tuesday.
Two doormen at the club, known as Misty's, were taken to hospital - one with stab wounds, the other knocked unconscious.
Three men and a woman, all from Hove, have been arrested.
The men, aged 52, 34, and 29, are all in custody on suspicion of causing grievous bodily harm.
The 30-year-old woman is being held on suspicion of aiding and abetting actual bodily harm.
The doormen were taken to the Royal Sussex County Hospital, Brighton, for treatment to their injuries, none of which were considered life-threatening.
Det Sgt Duncan Lloyd said inquiries were continuing into what is being treated as an isolated incident.
The force is appealing for witnesses to come forward.
