Nov. 3 (UPI) — One of two suspects arrested at the scene of the weekend’s mass stabbing on a British train has been released, according to British authorities who continue to investigate.

Eleven people were injured in the Saturday evening attack on a train in Cambridgeshire, located about 37 miles north of London.

Two people — a 32-year-old man and a 35-year-old man — were apprehended at the scene.

In a statement Sunday night, British Transport Police said the 35-year-old man has been released, with no further action required.

“It was reported in good faith to officers responding to the incident that he was involved in the attack, and following enquiries we can confirm that he was not involved,” authorities said.

The 32-year-old, who’s been described as a Black British national, remains in police custody on suspicion of attempted murder.

Police on Sunday night identified him as a Peterborough resident.

Authorities were notified of the stabbing at 7:42 p.m. local time Saturday on the train from Doncaster to London King’s Cross. The 32-year-old suspect is believed to have entered the train at the Peterborough station.

A knife was recovered from the scene.

Ten people were transferred by ambulance to the hospital while an 11th victim arrived later on their own.

Five of the victims have since been discharged, according to authorities that said of the six remaining hospitalized, one is in life-threatening condition.

Authorities identified the most severely injured victim as a member of the London North Eastern Railway.

Following a review of surveillance footage, authorities believe that if it were not for his actions, more people would have died.

“The actions of the member of rail staff were nothing short of heroic and undoubtedly saved people’s lives,” Deputy Chief Constable Stuart Cundy said, though it was not clear what actions the employee took that saved lives.

David Horne, managing director of LNER, said the attack was “deeply upsetting” and that over the coming days they will continue to cooperate with authorities on their investigation.

In a statement on X, LNER said it expects to run a normal service on Monday.

The incident occurred just days after the British government announced it had seized a record number of knives — nearly 60,000 — from England and Wales through its new knife surrender scheme.

Knife homicides in Britain have fallen by nearly 20% while knife crime overall has dropped for the first time in four years, according to government statistics.
