A man has been arrested after a laser pen was shone into the cockpit of a police helicopter.

The pilot and crew of the National Police Air Support helicopter from Wattisham were dazzled seven or eight times as the chopper flew over Gorleston at about 1.15am this morning.

The helicopter was able to identify the address from which the laser pen had been shone from using its thermal imaging cameras.

The crew guided officers from Norfolk police to the back of a property in Devonshire Road, Great Yarmouth, where a man was spotted in the garden shining a green laser into the helicopter's cockpit.

A spokeswoman for Norfolk police said a 34-year-old man from Winterton-on-Sea was arrested for endangering an aircraft and seized a laser pen from inside his address.

She said: 'He has received a cautioned for recklessly or negligently acting in a manner likely to endanger and aircraft or a person in an aircraft.'

Great Yarmouth police tweeted just before 4am this morning that a man had been arrested, with the hashtag of #endangeringaircraft. The force also posted a photograph of the laser pen.
