Two women were sexually assaulted while queuing to see the Queen lying in state, a court heard.
Adio Adeshine, 19, is said to have exposed herself and pushed into the funeral from behind as they waited in line at Victoria Tower Gardens on Wednesday night.
He is said to have gone down the Thames in an attempt to evade police officers, before going out and being arrested.
Adeshine was remanded into custody on Friday after appearing at Westminster Magistrates Court charged with two counts of sexual assault and two counts of violating a sexual assault restraining order.
Thousands of people lined up to see the late monarch stretched for kilometers through central London, as thousands lined up to pay their respects.
