A nursery worker was slashed after being attacked by three women who shouted "Allah", her colleague has said.
The woman was set upon as she travelled to work at a nursery in Wanstead, north east London.
The colleague, who did not want to be named, said the victim had "three Asian girls behind her chanting the Koran, 'Allah"'.
She added: "They pulled her to the ground, punched her, kicked her. One of them pulled out a knife and cut her arm from her wrist to her elbow.
"The police turned up, the ambulance cleaned her wounds up."
A Metropolitan Police spokesman said they were called at 9:36am on Wednesday to reports of an assault in Hermon Hill.
He said: "Officers and London Ambulance Service attended and found a woman, aged in her 30s, with a slash wound. Her injuries are not life-threatening.
"She has been taken to an east London hospital as a precaution.
"The suspects fled the scene prior to police arrival in an unknown direction.
"No arrests have been made. Enquiries continue."
