A 29-year-old man was questioned by police last night after he allegedly aimed a laser pointer at a helicopter while it was in the air.
The first laser strike occurred early in the evening while the police helicopter was being flown over Armadale.
At 9.45pm, the helicopter was again repeatedly struck by the green laser.
Officers narrowed down the area where the laser was coming from before making their way to the backyard of a Seville Grove home.
The 29-year-old will be summonsed for causing fear with a laser or light to people in conveyances.
