PASSENGERS hid in the toilets as one screamed “I’ve been stabbed” and another was slashed in the neck while protecting a young girl during a train knife rampage last night.

The LNER service from Doncaster to London made an emergency stop at Huntingdon, Cambridgeshire, amid the horror attack on Saturday that left nine people fighting for their lives.

Armed cops raced to the scene as British Transport Police declared a “major incident” – with two arrests made and counter terrorism police confirmed to be supporting the investigation.

A witness told The Times frantic people were hiding in the loos to avoid getting “stamped on” during the chaos, while another called Gavin told Sky News that a victim had said: “They’ve got a knife, I’ve been stabbed.”

He added as the train came to a stop the passenger – who was “extremely bloodied” – was “basically on the floor” as they tried to flee the attackers.

It’s understood a man with a knife was seen being confronted on the platform by armed officers before being tasered and restrained.

Gavin said officers told him a suspect “was a black male wearing all black”.

He added: “At the back of the station, people started shouting ‘get down get down’ and he was waving a knife, quite a large knife.”

The train involved was the 6.25pm service from Doncaster to London King’s Cross – with horror unfolding at 7.39pm.

Ten people were rushed to hospital with nine suffering life-threatening injuries, BTP confirmed.

Witness Olly Foster told the BBC he heard people shouting “run, run, there’s a guy literally stabbing everyone”, and said he initially believed it was a Halloween prank.

But as he moved down the carriage his hand became “covered in blood” after leaning on a chair – and said he saw an older man sustain head and neck injuries after blocking an attacker from stabbing a young girl.

Other passengers then worked to try and stem the bleeding from his wounds.

Olly claimed passengers were ushered out into the station, adding: “There were multiple people who had been stabbed.”

One eye witness described the scene on the train as “horrific” and “pure chaos”.

They told the Sun: “There was blood everywhere, it was a terrible scene, really violent. It was like something from a film.

“It didn’t feel real and just sparked pure panic onboard. Shocked onlookers were shaken and traumatised.”

Shocking footage shows police cars and ambulances flooding the roads outside of the station, as officers raced along the platform before boarding the train.

At one point, cops responding to the incident declared “Plato”, the national code word used by police and emergency services when responding to a “marauding terror attack”, before this declaration was later rescinded.

Forensic teams and sniffer dogs swept the station, with emergency responders seen working on the tracks, while the scene was sealed off to the public.

Evacuated passengers were reportedly being loaded onto coaches to London.

Prime Minister Sir Keir Starmer said the attack was “appalling” and offered his thoughts to all those affected.

Meanwhile, Home Secretary Shabana Mahmood said: “I am deeply saddened to hear about the stabbings in Huntingdon. My thoughts go out to all those affected.

“I am receiving regular updates on the investigation. I urge people to avoid comment and speculation at this early stage.”

Shadow Home Secretary Chris Philp called the stabbing rampage a “brutal mass attack”.

BTP said last night: “We can confirm that at 7.42pm today (1 November) British Transport Police were called to reports of a multiple stabbing on board the 6.25pm train service from Doncaster to London King’s Cross.

“Officers immediately attended Huntingdon station alongside paramedics.

“Armed police from Cambridgeshire Police boarded the train and arrested two people in connection to the incident who have been taken to police custody.

“Ten people have been taken to hospital with nine believed to have suffered life-threatening injuries.

“One is being treated for non life-threatening injuries. There have been no fatalities.

“This has been declared a major incident and Counter Terrorism Policing are supporting our investigation whilst we work to establish the full circumstances and motivation for this incident.”

Force Chief Superintendent Chris Casey said: “This is a shocking incident and first and foremost my thoughts are with those who have been injured this evening and their families.

“We’re conducting urgent enquiries to establish what has happened, and it could take some time before we are in a position to confirm anything further.

“At this early stage it would not be appropriate to speculate on the causes of the incident.

“Our response is ongoing at the station and will be for some time. Cordons are in place and trains are not currently running through the area, and there are also some road closures.

“I thank the public for their patience and their cooperation this evening which has already greatly assisted our policing response. We will update you again as soon as we have more information.”

A “large-scale response” was deployed by the East of England Ambulance Service.

A spokesperson says numerous ambulances, tactical commanders and its Hazardous Area Response Team were at the scene.

Critical care teams including the East Anglian Air Ambulance and Essex and Herts Air Ambulance also attended.

Meanwhile, a Do Not Travel warning has been issued for LNER passengers, with lines such as Thameslink also telling customers to check before they travel.
