PHNOM PENH, Nov. 8 -- Cambodia had freed a tourist from China's Hong Kong who was arrested Saturday morning for flying a remote-controlled miniature aircraft over the Royal Palace, a senior police officer confirmed Sunday.

The man was identified in a police report as Wong Tiga China, 40.

"We decided to release him on Saturday evening after we found that he had no any bad purposes in flying the drone over the Royal Palace," Sieng Sen, director of the Interior Ministry's Internal Security Department, told Xinhua.

"We educated him about the ban on drones in Phnom Penh and had him sign a contract to promise not to do it again," he said.

The Phnom Penh Municipality has banned flying drones without a permit since Feb. 16 after a German male tourist flew his camera-toting drone into the Royal Palace and was spotted by Queen Mother Norodom Monineath as she performed her daily exercise routine.
