Police have come under attack in a number of violent incidents over the weekend.
Colleagues had to help two officers escape from their car in Ballymena on Saturday night after a man wielding an axe smashed the windscreen.
The officers were responding to reports of suspicious activity in Kew Gardens shortly after 1am yesterday when their car was surrounded by a group of people.
A man armed with an axe smashed the windscreen while another man was seen carrying a machete. Two male police officers escaped the vehicle with the help of colleagues who arrived at the scene.
One man in his 20s and another in his 40s were arrested later yesterday morning.
Meanwhile, police were attacked by stone throwers while investigating reports that petrol bombs were being thrown in the Ballybeen estate in Dundonald.
Shortly after 10.40pm on Saturday the PSNI received reports that petrol bombs had been thrown in the Craignish Crescent area. Officers responding to the incident came under attack from people throwing stones and other missiles.
Three petrol bombs were thrown at police vehicles, but no damage was caused and no one was injured. Inquiries into the incident are continuing.
