A man was hit with bottle in a city nightclub leaving him needing hospital treatment.
The 33-year-old was in Zeros club in Lockyer Street, standing near the bar of the 'top bar' when he was attacked sometime between 4am and 4.15am on Sunday.
Police say he was struck around the forehead by another man wielding a bottle.
The victim was treated by paramedics before being taken to Derriford Hospital where a one inch cut to his forehead was glued.
He was discharged the same day.
Detectives believe there was a large number of people in the 'top bar' at the time of the incident and are keen to hear from independent witnesses.
