Police are appealing for witnesses after a fight involving two men and a woman in Bexhill.
Shortly after midnight on Thursday 31 July, a man and a woman were seen being chased in Sackville Road by a man who struck one of them over the head with an object.
The victim, a 56-year-old man from St Leonards, suffered a cut to the head that needed stitches.
PC Sally Waldron said: “This was a noisy confrontation so there may be a number of people who saw or heard what happened but who have not yet come forward.
“I would urge anyone with any information to speak to us.”
A 38-year-old woman and a 32-year-old man, both from Bexhill, and a 56-year-old man from St Leonards have been arrested on suspicion of affray.
All three were questioned before being released on bail until 8 September.
