Two men have been charged after disturbances in the Castlemara estate in Carrickfergus on Friday night.
A 36-year-old man has been charged with causing a dangerous vehicle to be on the road.
While another man (36) was charged with riotous behaviour.
Police said they responded to reports that a large crowd of males, some masked and carrying weapons, had gathered in the area.
The Fire Service dealt with at least one large blaze in the town.
Superintendent Emma Bond said: "Reports suggested some of the males were masked and may have been armed with weapons such as hammers.
"Officers attended and dispersed the crowd seizing a number of items including a crossbow."
Both men are to appear before Belfast Magistrates Court on July 28.
