Police in the North West are being forced to respond to thousands of laser pen incidents resulting in calls for them to be classed as offensive weapons.
Since 2014 there have been 1039 police reports involving laser pens in Greater Manchester including shining them into aeroplane cockpits, at oncoming traffic and into people's front rooms.
Cheshire Police released figures of 284 laser-related incidents, meaning the actual number in the region is unknown as Merseyside and Lancashire constabularies' figures have not yet been released.
In response, a pilot's union has warned the consequences could soon be disastrous and called for a change in the legislation to class them as offensive weapons.
Freedom of information requests by the Press Association revealed Greater Manchester Police had dealt with 1,039 incidents since 2014, with 156 of them involving aircraft.
Stephen Landells, flight safety expert at the British Airline Pilots Association (Balpa), warned of the possible consequences for single-pilot aircraft and helicopters as the power of lasers available to the public continues to increase.
Mr Landells said the law needed to change so people had to have a good reason to be carrying a laser, which would allow the police to act when they had reasonable suspicion of misuse.
