Subway drivers are refusing to stop at some stations in Paris because of a surge in violent crime at some stops, it has emerged.

Frightened drivers say they are not calling at certain stations in the French capital's north east in order to 'protect passengers' and themselves.

Some stations are increasingly being used by crack dealers, they say, with Marx Dormoy on line 12 and Marcadet-Poissonniers on lines 12 and 4 said to be among the worst hit.

According to The Local, the Unsa union representing drivers said the 'number of attacks on travelers and RATP staff is becoming increasingly dramatic'.

The union's Jean-Marc Judith said: 'Between the brawls that occur on the platforms, which sometimes end up happening on the train or across the tracks, you could hit someone, or crush them.'

Talks over security in the area are set to take place on January 19.

It comes as it was claimed a man was stabbed to death on the Paris metro as witnesses filmed and posted photographs on social media instead of helping.

Andy Brigitte, from Martinique, was knifed in an attack at the Châtelet-Les Halles RER station in Paris after a row with another passenger.

The 22-year-old mechanic, who had been living in the Essonne region of France, lay in agony on the ground as onlookers filmed and posted images online, according to French media.

His mother, Linda, said 'no one lifted a finger' as her son was dying.

French news magazine L'Obs reported wrote that Brigitte 'agonised on the ground ... while passengers, rather than help him, filmed his agony and posted images' on social media.

Many were left disgusted by the ghoulish behaviour of passers-by, with Twitter users setting up a Chatalet hashtag to hit out at their response.

According to Euronews, one wrote: 'Oh ok. In 2018, we die in front of a camera without any help.'

Emergency crews were called during rush hour at 6pm but Brigitte was declared dead at 7.30pm.

A 33-year-old from Melun, south of Paris, has been arrested.
