Police are investigating a racially aggravated assault which left a woman with serious injuries to her face and head.
Nikki Hurst, 32, said she was attacked by three Asian males, two of which were wearing school uniforms, as she was walking alone along Lady Ann Road in Batley, Yorkshire.
After being verbally abusive towards her, the attackers pushed her to the ground and kicked her.
During the attack she suffered a large gash to her forehead and serious facial injuries.
A video showing Ms Hurst's injury has been circulated widely on social media.
West Yorkshire Police said they had been conducting CCTV enquiries since the attack, but had "exhausted all obvious lines of enquiry".
Detective Chief Inspector Tony Nicholson, of Kirklees CID, said: “Detectives from Kirklees CID have been carrying out an extensive investigation into this racially aggravated assault last month.
“At this time we have exhausted all obvious lines of enquiry and I would urge anyone who was in the area at the time to come forward with any information about the incident, no matter how insignificant it may seem.
“Staff from Kirklees CID will continue to support the victim throughout the investigation and will continue to seek out the persons responsible."
Anyone with any information is asked to contact the police via 101 quoting crime reference 13170506171 or Crimestoppers anonymously on 0800 555 111
