Shomrim, the Jewish security group, has released CCTV footage of a Jewish woman being kicked and beaten by two people on a dark street in Stamford Hill, north London.
The security group said the assault left the victim unconscious.
They said on X/Twitter: “The brutal attack ended after the two female offenders kept on kicking the unconscious victim in the head before laughing over her body and, according to witness reports, saying joyfully she's ‘dead’!
“She was left collapsed and unresponsive in a puddle and appeared unconscious for a few minutes.
“Volunteers have spent all night recovering CCTV, searching for witnesses and supporting the victim and her family.”
The group added that police were very keen to speak to two females and appealed for witnesses to come forward.
Police said the incident, which involved a 20-year-old woman, took place at 4:30pm on Thursday 7 December.
The woman was assaulted and her bag was stolen, police said. Following the incident, the suspects ran off towards the A10. The woman sustained bruising but did not require hospital treatment.
Detective Inspector Mike Herrick, who is leading the investigation from the robbery unit, said: “This was a shocking incident and terrifying experience for the victim who was lucky to not receive more serious injuries. We don’t underestimate the psychological impact of offences such as these and we are offering her every support as we work to identify the suspects.
"We know footage of the incident has been widely shared on social media and understand that there will be added concerns about the motivation behind the attack. We will of course keep an open mind about the motive and continue to work closely with the local community to allay any fears.”
