A man carrying a knife has threatened Polish residents of a Co Antrim housing estate in a racist attack.
The windows of a house were smashed shortly before 3.30am yesterday.
A man then entered the house in the Carnany Park area of Ballymoney and assaulted one of the residents and threatened others who were present with a knife.
It is believed he also went into another house armed with the knife and threatened those he found in the property.
He then returned to the original house and damaged a fence outside.
When police arrived at the scene they were obstructed by a number of people. The PSNI later described the incident as a “hate crime”.
A 19-year-old man was later arrested in the area for assault, possession of an offensive weapon and criminal damage.
Two other males were arrested at the same time for public order offences and assault on police.
North Antrim MLA Mervyn Storey said the victims had done “nothing whatsoever to provoke such an assault on their property or person”.
