In a police interview Warren, of Eagle Mount, admitted the offence and said he was using the laser to point out the helicopter in the sky while recording it on his phone.
Sgt Michael Hayes said: “While the person the police helicopter was searching for during this incident was ultimately located, shining the laser beam in its direction was incredibly dangerous and could have seriously hindered their efforts to locate someone in need of help.
“The sentence handed to Warren should serve as a reminder of how serious this offence is considered.
“I hope it also reminds people of the risks associated with lasers, which some people may think of as a harmless device.
“This is far from the case and can have very serious consequences.”
