A total of six people have now been arrested as part of an investigation into a double stabbing in Bradford, police said.
West Yorkshire Police was called to Seymour Street, off Leeds Road, at about 22:15 BST on 11 May, where two men were found injured in the street.
A 31-year-old remains in hospital with serious but not life-threatening injuries, the force said.
Two men were held by police on Friday and remain in custody, with four others released on bail. The arrested men range in age from 22 to 37.
Detectives still hope to speak to further people with information about the incident or those with useful video footage.
