A 28-year-old man has been treated in hospital for serious injuries after being attacked by four teenagers.
The man had been walking on Paisley Road West close to Midlock Street at about 07:15 on Wednesday 12 April when the incident happened.
Police Scotland said he was surrounded by the group, and punched and kicked to the ground before being robbed of his mobile phone.
Detectives described it as a "shockingly violent attack".
The victim was taken by ambulance to the Queen Elizabeth University Hospital where he was treated for serious injuries, including stab wounds, and later released.
It is believed the group of teenage boys, aged between 15 and 19, made off in the direction of Midlock Street.
