A 46-year-old man has been arrested after an Atomic Kitten singer reported being sexually assaulted on a train to Bromley.

Natasha Hamilton said a man “pushed his penis” against her on a train from London Bridge to Elmstead Woods on October 10.

British Transport Police released a photo appeal to find the suspect who has since been arrested.

A spokesman said the man, from Wood Green, has now been released under investigation.

After the sexual assault, Natasha wrote on Twitter: “This vile excuse of a man just had his penis pushed up against me while on this overground train from London Bridge heading to Elmstead Woods.

“I thought it was a bag until I felt him heavy breathing down my neck. I am appalled and calling the transport police when I get off.”

She later wrote: “Honestly I am shaking and feel so violated now. But more than anything I am so angry. This has to stop happening to people.”

British Transport Police thanked the public for helping to share their appeal which led to the arrest.
