Police have arrested four people as part of their investigation into the stabbing of a teenager in Co Down.
Three women, aged 17, 20 and 35 and a 23-year-old man are helping police with their inquiries.
The teenager, aged 18, suffered serious injuries after being stabbed early this morning at a house at Windmill Park in Ballynahinch.
His injuries are not believed to be life threatening.
Police are investigating whether there is any link to a series of other disturbances in the same area on Saturday night.
Windows of three houses, three cars and a van at Windmill Gardens and Windmill Park were smashed by a group of youths, at least one of whom carried a baseball bat around 9pm.
They also tried to enter a number of properties.
Two males in their late teens were arrested on suspicion of criminal damage, but were released later, pending further inquiries.
