An injured man remains in hospital after being found by police responding to reports of a large group of men fighting in Botanic Gardens in south Belfast.
The man, aged in his 20s, suffered injuries to his leg, face and head in an assault at about 9.45pm on Friday.
A 31-year-old man has been arrested on suspicion of grievous bodily harm with intent and possession of an offensive weapon with intent to commit an indictable offence.
He remains in police custody.
PSNI Chief Inspector Kelly Moore said: “We know there were large numbers of people in the area last night, around the time this vicious assault was reported to us, and I want to appeal to anyone who was there and who witnessed what occurred, or who may have footage of it, to get in touch with our detectives at Musgrave CID by calling 101.
“Alternatively, call Crimestoppers on 0800 555 111.”
We will continue to engage, explain and encourage people to make the right choices and we will enforce when necessary. Each and every one of us has a personal responsibility to follow the NI Executive regulations and do everything we can to stop the spread of Covid-19.
Chief Inspector Moore added: “I understand that, with the sunny weather, people want to be outdoors and make the most of the sunshine.
“However, the public should be well aware of the advice from our public health partners and the Government about social distancing and movement and, on that basis, we would encourage people not to congregate in popular spots, as others may have the same idea and social distancing may not be achievable.”
Social distancing measures remain in place across Northern Ireland, in an effort to limit the spread of the coronavirus.
However, large gatherings have been reported at a number of spots – including Ballyholme beach in Co Down, where disorder occurred on Friday night and four teenagers were arrested.
