Aviation regulators are seeking help from local police to tame the increase of small drone operators endangering aircraft and people on the ground.

The Federal Aviation Administration Thursday issued a 12-page guide to law enforcement agencies on how to handle encounters with unmanned aircraft operators and gather evidence in the event legal action is needed.

“The proliferation of small, relatively inexpensive unmanned aircraft presents the Federal Aviation Administration with a challenge in identifying people who don’t follow the rules of the air or who endanger the nation’s airspace,” the agency said in a press release on its website.

The release is part of the agency’s response to growing safety incidents as thousands of people without aviation experience have begun flying small unmanned aircraft. The FAA logged 193 cases of drones flying near aircraft, buildings or crowds from Feb. 22 through Nov. 11.
