Suspect in custody after laser pointer disrupts HAWC1 flight
CALGARY - Calgary police took a suspect into custody early Tuesday morning after the flight of the HAWC1 helicopter was disrupted by someone on the ground with a laser pointer.
The helicopter was airborne in support of police operations late Monday night when a strike by a laser impaired the vision of the chopper crew, police said in a statement.
A police investigation pinpointed an address in northeast Calgary where the laser is believed to have originated, and a suspect was taken into custody.
The Calgary Airport Authority closed one runway as a precaution to ensure the safety of incoming aircraft, police added.
A police investigation is continuing.
