PSNI officers arrested a 17-year-old teenager in Derry last night on suspicion of shining a laser light at a police helicopter.

Officers say the arrest was made on suspicion of endangering the safety of an aircraft.

Superintendent Mark McEwan said, "the police helicopter was above the city in support of officers responding to reports of suspicious activity on the ground.

"The seventeen-year-old boy was spoken to in the presence of his parents," he added.
