A nursery worker has been stabbed on a London high street by three young women reportedly chanting “Allah,” but police say the incident was not related to terrorism.

Karrien Stevens, who runs the Little Diamonds nursery in Hermon Hill, confirmed that one of her employees, aged in her 30s, was stabbed in the arm while walking to work on Wednesday morning.

The victim was on Wanstead High Street in north London when she was attacked.

Although Stevens reported the attackers chanted “Allah” as they carried out the assault, police have confirmed they are not treating the incident as a terrorist attack.

Emails were sent out to parents saying local schools had been put on “lockdown” following the incident.

Stevens said the attackers pulled her employee to the ground before stabbing her in the arm.

They then fled the scene when a man ran to the victim’s rescue.

“When she got to work we couldn’t believe it and called the police straight away,” the nursery director said, according to the Daily Mail.

“It’s terrible, I’m absolutely horrified.”

According to a colleague, who asked to remain anonymous, the victim claimed she was attacked by “three Asian girls behind her chanting the Koran and ‘Allah.’”

“She’s okay, considering,” the colleague said.

“Obviously it’s a shock, she’s in shock. She was in tears and she had a cut right up her arm,” she said, according to the Daily Mail.

“Her stomach was hurting, she had marks all over her, her hair was pulled out.
