A Thai scout leader accidentally used the Korean women's bathroom during the World Scout Jamboree in South Korea, according to the National Scout Organization of Thailand.

Secretary-general Suthin Kaewphana said on Monday that the leader of a Thai scout squad bathed in the women's room because he did not see a sign designating if for women. It was unintentional. He even sang while bathing.

A Korean scout leader heard a man singing in the woman's bathroom, and called security, Mr Suthin said.

Jamboree officials questioned the Thai scout leader and he explained how he had accidentally entered the  women's bathroom, and they did not take any disciplinary action, Mr Suthin said.

The incident was reported to local Korean police, who held the Thai official for questioning.

The 25th World Scout Jamboree is being held in South Korea from Aug 1-12.

After the bathroom incident, it was reported that dozens of South Korea scouts decided to withdraw from the jamboree in protest.
