The SDLP has condemned rioting in Portadown overnight in which six PSNI officers were hurt.
A police spokeswoman said over 100 people were involved in the throwing of missiles and the damaging of vehicles in the High Street and Edward Street area.
A police officer sustained "serious facial injuries" and a female officer kicked an punched by a group of men, the spokeswoman said.
Two men were arrested. A 30-year-old man is due to appear before Craigavon magistrates next month charged with disorderly conduct and assault. Another man was freed on bail pending further inquiries.
The SDLP's Upper Bann MLA Dolores Kelly said the violence may have been a reaction to riots in Dublin yesterday.
She said: "Whether this is related to the violence in Dublin or not makes no difference whatsoever. Violence of this nature is wrong and cannot be tolerated. Just like the scenes in Dublin earlier in the day, I have no doubt that the violence in Portadown was orchestrated by a few bad apples of our society."
It was "particularly horrific that a female police officer was assaulted so viciously", she added.
