A 52-year-old man from Watford has been arrested after a video was released of a Tube passenger using "racist language" on board a train in London.

British Transport Police said the man was arrested on suspicion of a racially aggravated public order offence.

"An investigation was launched after we were made aware of a YouTube clip of a man using racist language on board a Bakerloo line train," police said.

The man was bailed pending further inquiries.

The incident is believed to have happened on Tuesday at about 21:00 BST.

He was bailed to return to a police station on 30 October.

British Transport Police have appealed for witnesses.
