Four men have been arrested following a night of chaos in north Belfast.
Shortly after 2.30am police received a report that a car parked outside a house on Ballysillan Avenue had been damaged by a petrol bomb.
A short time later "some form of altercation" took place outside a house on Silverstream Road.
A 29-year-old man sustained a stab wound to his lower abdomen during the incident. His injuries are not considered to be life threatening.
Three men are then reported to have forced their way into a house on Ballysillan Avenue, before assaulting the male and female occupants with what were described as batons.
The 19-year-old man and 21-year-old woman sustained bruising to their bodies as a result.
Police responded and arrested a 19-year-old man on suspicion of attempted murder and a 29-year-old man on suspicion of aggravated burglary at the scene. Two other men, aged 32 and 34, were arrested in the area on Sunday afternoon.
Detective Inspector Kerry Brennan said police were doing all they could to apprehend those involved.
“This must have been a terrifying experience for local residents in the area and I wish to reassure the local community that Police are doing all they can to identify those responsible for these incidents and bring them before the courts," she said.
“I am appealing to anyone who was in the area at the time and who witnessed the incidents or anyone who knows anything that can assist us with our investigation to contact detectives in Musgrave on 101, quoting reference 232 10/03/19.
"Alternatively, information can also be provided to the independent charity Crimestoppers on 0800 555 111 which is 100% anonymous and gives people the power to speak up and stop crime.”
Update - Three men aged 19, 32 and 34 were released on bail pending further investigation on Monday morning.
A 29-year-old man remains in custody.
