An alarming incident unfolded when a man wielding a knife attacked 11 people aboard a train bound for London, ominously telling one passenger, “The Devil is not going to win.”

The chaos erupted on the 6:25 service from Doncaster, with the assailant launching a 14-minute assault through the train’s carriages.

Thanks to the driver’s quick response, the train made an emergency stop at Huntingdon station, where police were ready to intervene.

Disturbing video footage, obtained by the Daily Mail, captures the moment terrified passengers raced for safety along the platform, while the hooded suspect casually followed with a knife in hand.

Authorities swiftly subdued the attacker using a taser, leading to his arrest. Medical teams were on hand to transport nine severely injured passengers to the hospital and provide immediate care to other shaken travelers.

While terrorism has been ruled out, sources confirmed that the suspect had a history of mental-health issues and was known to the authorities.

After a second man arrested on the train was released without charge, British Transport Police (BTP) were last night holding a 32-year-old black British man, from Peterborough, on suspicion of attempted murder. 

He is said to have begun his onslaught on Saturday minutes after boarding the train in his hometown, where the Doncaster to London King’s Cross service arrived at 7.30pm.

Terrified passengers were seen running along Huntingdon station’s platform 2 trying to escape

Within minutes of leaving the station, the knifeman launched his stabbing spree and the alarm was raised in Coach J, as passengers began to flee through the carriages. He then made his way down the corridor towards the back of the train, stabbing as he went, with wounded passengers’ blood soaking the seats as they fled ahead of him.

Some locked themselves in lavatories, others hid in the cafe section, pulling down the shutters.

One woman, Dayna Arnold, 48, boarded the train with her partner, Andy Gray, 37, minutes before the incident began. The couple were in Coach J and she was separated from Mr Gray as people ran for their lives.

Ms Arnold had fallen to the floor when the suspect stood over her with a 6in blade and she begged him not to hurt her.

She said: ‘I was running and when I looked back I saw the knifeman running after me. I fell down and I said, “Please don’t”. Something shifted in his face and he just carried on. He said, “The Devil is not going to win”.’

The train then made an unscheduled stop at Huntingdon station at around 7.41pm, where officers were waiting.

Exclusive videos obtained by the Daily Mail showed blood-stained passengers sprinting down the platform to get away once the train had stopped.

In the footage, a rail worker can be seen walking backwards keeping his eyes on the knifeman as he urged the public to ‘move down, move down’ and ‘run, please’.

 Video then showed the attacker had jumped down from the platform and crossed a section of track, before climbing a fence and walking through the car park brandishing his large blade. Separate video taken by a taxi driver then shows the knifeman shouting ‘kill me, kill me’, as he is bundled to the ground by half a dozen armed officers.

Two people remain in a life-threatening condition in hospital, including an LNER worker who was being hailed a hero last night for trying to stop the attack.

Stuart Cundy, Deputy Chief Constable of the BTP said: ‘My thoughts are with those injured and their families – especially the brave member of rail staff whose family are being supported by specialist officers. Having viewed the CCTV from the train, the actions of the member of rail staff were nothing short of heroic and undoubtedly saved people’s lives.’

Police originally designated the incident as coming under ‘Code Plato’, meaning it was considered a ‘marauding terror attack’, but terror police were later removed from the inquiry.

A second man, described as a 35-year-old Briton of Caribbean descent was arrested but was yesterday released.

Superintendent John Loveless of British Transport Police said the force ‘declared a major incident, and counter-terrorism policing were initially supporting our investigation. However, at this stage, there is nothing to suggest that this is a terrorist incident’.

David Horne, managing director of LNER, said: ‘We are deeply shocked and saddened by the incident and our thoughts and prayers are with everyone affected, particularly our colleague who remains in a life-threatening condition.

In one video, a man was seen holding a rag to his head as crimson-coloured blood seeped through

‘I would like to thank the emergency services for their quick and professional response and the care they provided to those injured. I would also like to recognise the driver, crew and our operational response colleagues for their bravery and quick actions.’

King Charles said he was ‘truly appalled and shocked to hear of the dreadful knife attack’ adding: ‘Our deepest sympathy and thoughts are with all those affected, and their loved ones.’

Home Secretary Shabana Mahmood praised the ‘exceptional bravery of staff and passengers’ on the train.

Tory leader Kemi Badenoch said the attack showed there was ‘clearly something going wrong with our society’. 

LNER services between London and Peterborough were expected to be disrupted until the end of the day.
