Police came under attack from a masked gang throwing petrol bombs after a shooting at a house in Londonderry.
Two men inside the Dove Gardens property escaped injury when the gang of four men opened fire on Tuesday night.
A number of shots were fired at the front door of the home at about 11pm.
The same gang later returned and threw petrol bombs and other missiles at detectives investigating the attack, it is understood.
One PSNI officer was injured during the violence after being hit by a stone.
SDLP Foyle MLA Pat Ramsey said local people were appalled by what had happened.
"This is an area populated by families, children and elderly people," Mr Ramsey said.
"Our communities have suffered from the obscenity and destructiveness of violence for far too long.
"The people are very clear in their desire to live in a normal society. As a representative of the people of this city, and speaking on their behalf, I totally condemn the attack."
Alliance Chief Whip Kieran McCarthy has condemned the incidents.
"These were despicable events. It is appalling that a PSNI officer was injured after being hit by a stone during the violence. My thoughts are with the officer and I wish them a speedy recovery.
"It is deeply troubling that two men were in the house at the time of the shooting and this must have been a very traumatic event. Those involved in these events must be brought to justice and I appeal to anyone with information to contact police immediately."
Police have said a motive for the shooting has yet to be established and have asked anyone with information to come forward.
