Keira Sands, of Sceptone Grove, was walking metres from her home on High Street before allegedly being beaten by two grown men in the middle of the street at about 11pm last Monday.
The 14-year-old was left shaken on the floor as the culprits ran off shortly after the attack, as her mum ran to the scene.
Now her mum, Nicola, is determined to get justice for her daughter.
“It’s absolutely disgusting what has happened to Keira - it was completely unprovoked and should never happen to anyone, never mind a young girl.
“She was taken away on a stretcher which was absolutely terrifying not knowing the extent of her injuries.
“She’s been left with a lot of physical and mental trauma from this. She’s got numerous bruises, two black eyes and bleeding in her eye.
“It’s absolutely heartbreaking to watch her go through this. She’s been terrified to leave the house and can’t stop thinking about what happened.
“We’re all living in fear that nothing’s been done. She doesn’t deserve this.”
Nicola is now campaigning for local police officers to do more to help her family as she believes work has stalled.
“It’s been a week and there’s not been any updates,” she added. “On the night it happened, we were told police made enquiries door-to-door but after that, nothing has been said.
“We’re still waiting for the case to be allocated which means even more days left in limbo for us.
“We understand it’s a complicated case, but there were at least three sets of CCTV footage and witnesses who saw what happened.
“Every day that we’re forced to wait for more news and updates is more time that Keira’s left devastated and shaken.
“The longer it’s left, the more people will stray away from what happened and make excuses.
“We need to be more involved in this to help find those responsible. These absolutely horrid men need to be taken off the street before it happens to another young girl.”
A spokesperson for South Yorkshire Police told the Chronicle officers are investigating the incident.
“Police were called at around 11pm on February 15 to reports of an assault in Shafton,” they added.
“It is reported that a 14-year-old girl was walking on High Street when she was approached by two men.
“Following a verbal altercation, the men assaulted her, causing her to suffer minor injuries.
“Emergency services attended the scene and the girl was taken to hospital via ambulance.
“An investigation has been launched to find those responsible. Police are appealing for anyone with information which might help our officers in their enquiries to come forward.
“If you can help, please call 101 quoting incident number 1044 of February 15.
“Alternatively, you can stay completely anonymous by contacting the independent charity Crimestoppers via their website.”
