An ‘extremely dangerous’ laser attack was carried out on a low-flying aircraft in Sleaford on Sunday.
Police are appealing for information about the incident, which took place as the aircraft was flying over the town at around midnight.
They were quick to condemn the action which in a Lincolnshire Alert email they described as a ‘laser attack’ and said was ‘extremely dangerous’.
A police spokesman said: “Shining laser devices towards aircraft while they are in flight is not only extremely dangerous but is a criminal offence under the Air Navigation Order.
“It can dazzle or distract a pilot and can prove a considerable threat to the safety and wellbeing of people onboard.
“These devices are not toys and while it may seem relatively innocuous to shine one at a flying aircraft we would like to remind people of the seriousness of that behaviour - both for those flying and for the individual/s acting in that manner.”
Any information should be passed to police on 101, quoting incident number two of April 13, 2015.
Such incidents are treated as a civil aviation matter and investigated by the police.
A Civil Aviation Authority spokesman said: “Shining a laser at an aircraft in flight is a serious risk to the safety of passengers and crew, as well as people living close to airports. During critical phases of flight, such as take-off and landing, pilots need to employ maximum concentration.
“Being dazzled and temporarily blinded by an intense light could potentially lead to flight crew losing control of the aircraft.
“Pointing a laser at an aircraft is now a specific criminal offence and we strongly urge anyone who observes a laser being used at night in the vicinity of an airport to contact the police immediately.”
Police say on this occasion the aircraft and pilot were not affected by the green laser light device.
