A young British woman was gang raped during an annual street music festival in central Paris, French police have said.

Investigators say the attack may have been filmed - which follows similar attacks at the same event.

A police source said the woman was found crying as she walked through Paris' 1st arrondissement in the early hours of Saturday morning.

The British victim had left a concert - one of hundreds of events held across France on June 21 to mark the "Fête de la Musique" - known as "Make Music Day" in English - before she was attacked and robbed.

She told police that a group of men approached her and took her to a secluded area, Le Figaro reports.

The Briton was picked up by police and firefighters and taken to the Cochin hospital.

Officials say the woman remains in hospital following treatment.

"The attack happened around the Châtelet-Les Halles forum in the early hours of Saturday morning," an investigating source said.

"She was walking back from a concert at the Olympia music venue and says she was approached by a group of men.

"They surrounded her, and attacked her, and the fear is that they recorded their actions using their mobile phones."

A similar attack took place at the Fête de la Musique in 2021 when a woman was surrounded in a street near the Champs Élysées.

The following day, a video appeared online and was used as evidence to locate the rapists.

The attackers have never been found and the case remains active.

It comes as five teenage girls were injected with an unknown substance as they attended another Make Music Day event.

The girls, aged 13-17 said they were dancing at an event in the Saint-Maur-des-Fossés suburb of Paris when they felt stings in their arms.

Police have not made any arrests in connection with the attack.
