Sickening videos capturing violent fights between groups of teens at various Wigan locations have been shared on Facebook.
The clips, which have seemingly been captured by youngsters involved in the attacks, have been shared more than 1,000 times - sparking concerns among parents of teenagers for their safety.
In one of the videos, a girl can be seen dragging another to the floor by her hair, punching her repeatedly in the face and kicking her while she lies defenceless on the ground covering her face with her hands.
At the same time, a number of male voices can be heard encouraging the girl to “use her knees”. After the attack, the film appears to capture footage of the young victim lying motionless on the floor.
In a similar video, which was allegedly filmed in Mesnes Park, a large group of teens can be seen fighting with each other as others follow them filming and laugh in the background.
The videos have sparked outrage among both parents and other teenagers who are calling for an end to the violence.
Warnings have been posted by concerned mums and dads urging others to keep their children away from “hotspots” such as parks and fast food restaurants.
One parent said: “Someone should’ve done something. Kids these days should be supporting each other not tearing each other down over a lad or a girl or hate, nevertheless it’s childish.”
Another woman told the Post that there have been an estimated 17 attacks launched by the same large group of youngsters in the past couple of weeks.
“My son told me it’s around 17 attacks,” she said. “They are claiming they are arranged fights but they aren’t - they are unprovoked.”
Charlie Holmes, whose on son was also attacked by the same group last week, said; "I felt sick, angry and upset when I saw these videos as my son and his girlfriend went through the same thing a few weeks ago and he broke down to me.
"Seeing my son like that makes me angry.
"Even though it's not my child I felt the same feeling. It's horrible that's why I have now sponsored an anti-bullying campaign."
The mum of a boy was set upon by a group of teens in Mesnes Park is urging people to report any fights to the police.
The woman, who wished to remain anonymous to protect her son, described how some of the people in the videos attacked him and to steal his mobile phone.
“He wasn’t the same following the attack,” she said. “He only remembers the first punch so I think he must have been concussed. His friends had to tell him. He’s not wanted to be away from the family since, which is unusual for a 16-year-old.”
