U.K. train attack survivor breaks her silence, revealing the knifeman’s terrifying reply.

A survivor of the UK train mass stabbing has described how she begged for her life, and the madman attacker told her “the devil’s not going to win.”

Dayna Arnold was in the same train car as the attacker when he began slashing at “anyone he could find,” during horrific scenes on board a London-bound train in the east of England just after 7:30 p.m. on Saturday.

“I was going with the crowd but then I got knocked into some seats. I looked back and saw the knifeman running so I slid down to the floor,” Arnold, 48, told the Sun.

She added: “He came at me with the knife and I begged, ‘Please don’t.’ Then something shifted in his face and he just carried on. I feel very fortunate to still be alive.”

Arnold, who was on board the train with friend Andy Gray, 37, recalled the attacker’s sinister words as he spared her life amid the mass slashing that left 11 people wounded, two of whom are still fighting for their lives.

“Then a minute or so later he came back through, looked at me again and said ‘the devil’s not going to win,’ and continued on,” she said.

One 32-year-old British man is in custody for attempted murder following the attack, which saw armed cops scrambled to the small market town of Huntingdon, Cambridgeshire.

A second man was detained, but later released without charge.
