Assistant Chief Constable of Greater Manchester Police, Chris Sykes, said: "We're pleased that the vast majority of people followed the Government's request to remain indoors and celebrate within their household or support bubble.
"It wasn't the way any of us wanted to enter the New Year, but we're grateful for the public's support.
"2020 has been a difficult year for everyone across the region, including our hard-working officers and staff. I'd like to thank them for rising to the unprecedented challenges we have faced.
"Unfortunately there were a number of incidents last night that required their continuing professionalism.
"I'm sure the right-thinking majority of our residents will join me in condemning this irresponsible behaviour, which puts lives at risk.
"I would urge people to remain strong during what will hopefully be the final few months of restrictions. Protect your loved ones, each other and our NHS by continuing to follow Government rules.
"If everyone does their part we can look forward to a brighter year ahead."
