Police on Wednesday sent a case to prosecutors accusing a man in his 50s of throwing raw eggs at the entrance to the office of Tokyo Metropolitan Assembly member Akihiro Suzuki on June 23.

The man, whose name was not released, allegedly egged the office the same day that Suzuki, 51, apologized at a news conference for sexist remarks he made to Assemblywoman Ayaka Shiomura on the floor of the assembly, sparking an uproar both at home and abroad.

The suspect reportedly admitted to police that he violated the Minor Offenses Law by throwing 30 raw eggs at the office in Ota Ward, which is where the man also resides, on the night of June 23.

"I couldn't forgive his behavior at the assembly's plenary session," he was quoted as saying.

According to police, the man said he was drunk at the time. After throwing 10 eggs from one carton, he bought two more cartons and went back to hurl 20 more eggs at the office, he reportedly said.

Police learned of the incident from a passer-by who saw the aftermath of the egging.

The suspect went to a nearby police box and turned himself in during the early hours of June 24. He underwent questioning on a voluntary basis, the police said.
