A man was arrested by New York City police for using a drone over the U.S. Open on Wednesday.

Daniel Feighery, 36, was arrested for using the unmanned aerial vehicle on empty courts near the U.S. Open match at about 9 a.m., RT reported.

He was caught at the National Tennis Center, during the quarter-final match between Serena Williams and Flavia Pennetta.

Feighery was charged with reckless endangerment, violent of a local law and failure to comply with a sign -- but it is not know what the sign said -- and his drone was confiscated, CNN reported, according to RT.

The Federal Aviation Administration has prohibited the use of drones for commercial or civil use, subject to certification, because the use of UAVs is governed by the same rules as all other aircraft.

"There are no shades of gray in FAA regulations. Anyone who wants to fly an aircraft-manned or unmanned-in U.S. airspace needs some level of FAA approval. Private sector (civil) users can obtain an experimental airworthiness certificate to conduct research and development, training and flight demonstrations," the FAA said on their website.

But drones are allowed if they are flown under 400 feet, except for large metropolitan areas like New York City.

An FAA spokesman told NPR that congested cities like New York are completely off-limits to drones, which is qualified as Class B airspace, RT reported.

Daniel B. Schwarzbach, the executive director of the Airborne Law Enforcement Association, told the New York Times after a previous incident, "We support the use of this technology, but we support its responsible use. Just go onto YouTube and you'll see tons of examples of people using these things irresponsibly: flying at altitudes of more than 400 feet or flying over bridges."

The FAA has estimated as many as 7,500 small commercial UAS may be in use by 2018.
