Seattle Police are investigating a report of a drone peeping into a woman’s apartment window.

Police were called to the downtown Seattle apartment complex on Sunday morning after she spied an unmanned aerial vehicle hovering outside the building. The woman said she was concerned the drone was looking into her apartment.

After calling police, an employee of her apartment building says he went outside and saw two men piloting the drone. They packed up their gear, which included a video camera, and drove off before police arrived. Authorities say they are checking for surveillance video that may help identify the men.

Drones and what role they should play in society have been a hot item in Seattle for quite some time. Last year, former Seattle Mayor Mike McGinn ordered the Seattle Police Department to abandon its plan to use drones after an uproar from citizens and privacy advocates.
