On December 1 2013, Kristian Larsen aimed a blue laser “like a light sabre” from his home in central Auckland towards the aircraft which was taking off from the police helicopter base at Mechanics Bay. The laser beam led police to Larsen’s location, where he was arrested.
The 44-year-old man is charged with endangering transport.

US: UPDATED - Las Vegas area man, previously convicted of aiming lasers at helicopters, does it again six times
James David Zipf had been convicted in Phoenix, Arizona in 2011 for aiming a blue laser at police helicopters. In May 2013 he moved to Henderson, Nevada, 12 miles from Las Vegas.
The indictment stated that Zipf aimed a laser at Las Vegas Metro Police helicopters six times between January 31 and February 12 2014. In one of the attacks, the pilot was so disoriented that he landed the aircraft and ended his shift.
At a detention hearing, Zipf was ordered to remain in jail. The judge said he had endangered the helicopter crews, was a threat to the community, was not truthful to federal agents, and was using drugs.
Zipf faces up to five years in prison and up to $250,000 in fines for each of the six counts.

UPDATED - September 24 2014: Zipf was sentenced to two years in prison. He also must undergo mental health and substance abuse treatment. A news reported noted that one of the flight officers in a February 3 2014 incident experienced a severe headache. From KLAS-TV
Michael Rademacher, a traveling maintenance man, had purchased the blue laser and used it to etch his initials on his work tools. On the night of March 21 2013, he was bored and decided to aim it at the police helicopter. One pilot said it was the brightest he had seen pointed at him. After regaining their bearings, the pilots identified the source of the beam and notified ground officers. Rademacher initially said he was not involved but he confessed after officers armed with a search warrant found his laser.
In September 2013, Rademacher pleaded guilty to one felony count of possession of criminal tools. As part of the plea bargain, the more serious charge of interfering with the operation of an aircraft was dropped.
If Rademacher violates probation, he will be imprisoned for 12 months. Rademacher also lost his job as a maintenance man due to his arrest and plea.
