Counter-terrorism police are involved in an investigation into a mass stabbing on a train which left nine people suffering with life-threatening injuries.
A man with a large knife is believed to have been shot with a Taser by police after going on a bloody rampage on a high speed train after it left Peterborough station in Cambridgeshire.
British Transport Police (BTP) said two people have been arrested over the stabbings which happened on the 6.25pm train service from Doncaster to London Kingâs Cross on Saturday.
Police said there have been no fatalities so far from the attacks which Prime Minister Sir Keir Starmer described as âdeeply concerningâ.
A tenth person suffered non life-threatening injuries.
BTP said a major incident was declared, and at one point declared âPlatoâ, the national code word used by police and emergency services when responding to a âmarauding terror attackâ, before the latter declaration was subsequently rescinded.
Witnesses have spoken of seeing a man with a large knife and passengers hiding in the toilets to escape the rampage, The Times reported.
One told the paper there was âblood everywhereâ and people were getting âstampedâ on by others as they tried to flee.
The witness said: âI heard some people shouting we love (you).â
The Sun said another witness described the attack as âlike something from a filmâ, adding: âIt was a terrible scene, really violent.â
One man, who gave his name as Gavin, told Sky News he believed he saw the suspect tasered before he was arrested.
He said: âEssentially, as they got closer to him, started shouting, like, get down get down.
âHe then was waving a knife, quite a large knife, and then they detained him.
âI think it was a Taser that got him down in the end.â
Video footage on social media showed scores of blue-light police cars and emergency vehicles in a station car park, and a team of armed police running towards the stationary train at Huntingdon station.
Officers wearing forensic suits, with a police dog, could be seen on the platform.
The attack is understood to have started shortly after the LNER train left Peterborough station.
Chief Superintendent Chris Casey said: âThis is a shocking incident and first and foremost my thoughts are with those who have been injured this evening and their families.
âWeâre conducting urgent enquiries to establish what has happened, and it could take some time before we are in a position to confirm anything further.
âAt this early stage it would not be appropriate to speculate on the causes of the incident.
âOur response is ongoing at the station and will be for some time.
âCordons are in place and trains are not currently running through the area, and there are also some road closures.â
