A suspect has been arrested after footage which appears to capture the alleged attempted rape of a woman on a train near Paris went viral, local media say.

Jhordana Dias, a 26-year-old Brazilian national, was allegedly attacked earlier this month. She told Le Parisien newspaper that the man boarded the train, pushed her and attempted to pull down her underwear.

Alerted by her screams, another passenger pulled out her phone to film. The footage captures a man fleeing as the train pulls into a station.

The incident has revived discussions around women's safety in France.

According to French media, a man was arrested on Friday evening by transport police in Mantes-la-Jolie, north-west of Paris. He was traced there by investigators, but it is unclear how.
