A woman has been arrested in connection with the death of a man who was attacked in Co Down.

Stefan Zait, 45, a fisherman who was originally from Romania, was assaulted in Ardglass just before 11am on Tuesday.

The 40-year-old woman was arrested last night and is being questioned by detectives.

A 20-year-old man who was arrested on Wednesday night remains in police custody.

A 23-year-old man was also detained after the incident but was subsequently released on bail pending further police inquiries.

PSNI Detective Chief Inspector Eamonn Corrigan said Mr Zait died from serious head injuries sustained during a "brutal and senseless attack" in broad daylight.

Officers are appealing for any witnesses, anyone with dashcam footage or anyone with any information to contact them.
