Tokyo police have arrested Japanese national soccer team midfielder Kaishu Sano on suspicion of sexual assault, local media said Wednesday.

The 23-year-old was arrested together with two acquaintances in their 20s for allegedly sexually assaulting a woman in her 30s at a Tokyo hotel shortly after 4 a.m. Sunday, according to Metropolitan Police Department officials. The police did not say whether the trio admitted the allegations.

Investigative and other sources said that the trio dined with the woman and her female friend in the Roppongi district in Tokyo's Minato Ward on Saturday night. The three apparently sexually assaulted the woman at the hotel in Bunkyo Ward after her friend left for home around 2 a.m. on Sunday.
