Police on Wednesday released a British tourist who shocked onlookers by swimming naked in the moat of Japan's Imperial Palace, concluding he had mental problems.
The bald, heavy-set and visibly agitated man was chased by officers around the palace for two hours on Tuesday. He dived into the moat then pelted them with stones.
"We decided to hand the man over to his friend without charging him as we concluded that his act was based on mental instability," a police spokesman said.
Bystanders snapped photos of the 40-year-old, whose antics were one of the top stories on Japanese television.
A British embassy spokesman confirmed the man was British and said he received consular assistance but declined further details, citing privacy issues. Media reports said the man lived in Spain.© Wire reports
