A former Saudi diplomat is under investigation for allegedly groping a woman at a Tokyo nightclub

Investigative sources said a former Saudi Arabian diplomat was referred to prosecutors on Friday over allegedly touching women’s breasts at a Tokyo nightclub earlier this year.

The 30-year-old man, who was posted at the Saudi Arabian embassy at the time, has already returned to his country without responding to police requests to appear for questioning, sources said.

According to sources, he is suspected of touching the breast of a woman in her 20s over her clothes at a club in Roppongi around 2:50 a.m. on July 15, in violation of Tokyo’s Nuisance Prevention Ordinance. The two didn’t know each other.

The woman then called the police, and the man told arriving officers that he had only touched her arms. He agreed to accompany officers during the interrogation, but later identified himself as a diplomat and left, sources said.

In October, police twice asked the Saudi embassy through the Japanese foreign ministry and others to ask the man to appear for questioning. However, he did not respond and returned to Saudi Arabia in November.

At the time, he enjoyed immunity under the Vienna Convention on Diplomatic Relations, which grants diplomats immunity from arrest.
