A number of police cars have been attacked in Strabane.
It happened on Monday evening as officers went to a house in the town's Ballycolman estate where there had been a sudden death.
SDLP Councillor Patsy Kelly condemned those responsible for the attack.
"This is about a group of mindless thugs who seem intent on attacking the police. It is a small minority who have brought Strabane into the headlines," he said.
"The police who were attending the scene were in ordinary police cars and not in land rovers and were attacked with stones.
"I would ask anyone who knows who these people are to report them to the police, because what has happened is totally disgusting."
Writing on the Strabane PSNI Facebook page, a police officer said their cars were attacked while attempting to deal with what was "a sensitive matter".
"These young people were well aware of the issue being dealt with but refused to desist from their behaviour."
The officer added: "Whilst we are trying to reduce the use of the Land Rover in dealing with calls, and I appreciate they can be quite noisy when driving around estates, it is behaviour like this that forces the police to use these heavy vehicles as they are less easily damaged."
