Two men have been critically injured in a stabbing in a bar in Birmingham city centre.
The men, aged 51 and 49, were stabbed at Bar Room Bar at the Mailbox shortly after 20:30 on Saturday, police said.
Two other men, aged 18 and 20, have been arrested. Police said one was detained at the scene and the other nearby after a chase on foot.
The injured men are in a critical but stable condition in hospital, West Midlands Police said.
Officers are still trying to trace a third man who left the scene.
The bar, overlooking the canal at the back of the Mailbox complex, remains sealed off while forensic tests are carried out.
Det Insp Harry Harrison, who is leading the investigation said it appeared to be a "a targeted attack" as a result of an ongoing dispute between two families.
Officers have appealed for anyone with information on the attack to come forward, which they said was believed to be part of an ongoing dispute between two families.
