Shocking footage has emerged of a group of girls attacking another girl outside the Cleethorpes Leisure Centre on Saturday night.
In the video, a girl can be seen punching another girl on the ground, while onlookers encourage her to "strangle" the girl, and laugh about what has just taken place.
The victim is also pulled by her hair to the floor as she attempts to get away from the attack.
After the attack appears to finish, the group of girls can be heard telling the attacker to follow the other girl and "strangle" her to the floor again and continue the onslaught.
It has been reported that other girls were assaulted by the group as well.
It is understood that an adult stopped their car and intervened to stop the attack in the end, and at least one girl was taken to hospital.
The incident is believed to have happened following a roller skating event at the Cleethorpes Leisure Centre.
The footage has been circulating on social media, and is understood to have been taken by the group of girls who were involved in the attack.
The woman who broke up the incident said:
I was driving down the seafront when my sister told me that her daughter would be leaving the Leisure Centre soon, so I said I would pick her up.
If anyone has any information regarding the incident they are being asked to call Humberside Police on non-emergency number 101, quoting log number 537 for the 14/12/19.
