TOKYO, July 13 (Xinhua) -- Three United States servicemen stationed in Okinawa, western Japan, were arrested early on Sunday on suspicion of trespassing on private property by parking their car there.

　　According to Japan's national police agency, the three arrested are all air men stationed at the U.S. Kadena Air Force Base in Okinawa.

　　They allegedly parked a passenger car in a 58-year-old man's private parking space in the city of Okinawa around 3:15 a.m. (1815 GMT Saturday) without his permission.
