A U.S. soldier has been arrested on charges of injuring the owners of a Seoul motel who rejected her stay for breaching service rules, police said Thursday.

   On June 6, the 31-year-old American sergeant allegedly hit the married couple who run the motel in central Seoul after they tried to block the soldier and her acquaintances from checking into one room, the Yongsan Police Station investigating the case said.

   The husband returned the money to the U.S. soldier after the group, including two American men and one other woman, tried to check into one room, and rejected their stay.

   The U.S. soldier, however, hit the husband and went on to hit the wife, who tried to stop the assault. The husband suffered a lumbar sprain that required three weeks of treatment in a hospital, while the wife's eardrum was ruptured, according to the police.

   Police said they have secured CCTV footage of the crime scene.

The U.S. soldier has denied all charges. (Yonhap)
