Assistant chief constable Andy Slattery said a "larger number of people than normal" were breaching the rules and the force had "numerous calls to parties" over the weekend.
He added: “A lot of people had pretty scurrilous reasons for travelling. Many admitted they shouldn’t be out but thought they would chance it anyhow.
“It’s been challenging, but the vast majority of the public has been really co-operative with our officers."
He added there had been a “small minority” of “difficult and abusive” rebels.
