Shocking moment woman headbutts victim in Belfast's Botanic Gardens

Shocking footage has emerged showing a mass brawl in a park in the middle of Belfast.
The huge fight broke out as university students sat in the park to make the most of the sunny weather, and shows a group of men fighting each other and a woman swinging punches.
One video shows a woman, wearing a long black and white dress with a thigh split and denim jacket, following another woman who is in the middle of calling the police.
The woman follows her, and knocks her sunglasses off her face.
The woman calling the police can be heard explaining the fight and telling police it's in the Botanic Gardens, a scenic part of the Northern Irish city close to Queen's University.
The fighting woman then yells: 'If anybody wants to f****** fight me in this f****** park, come on!'
Having had enough of hearing the police being call, the woman storms back up to the caller, and squares up to her.
She swings back and delivers a blow to the woman's neck.
A third woman intervenes, tries to split the pair up, but another man comes over and pushes her away.
Next, the woman headbutts her victim.
Speaking to Belfast Live, the woman who intervened said the attacker 'seemed possessed'.
She said: 'Just random people were being thumped and there was all this shouting like, "What the f*** are you looking at".'
The anonymous good Samaritan added: 'I just couldn’t get over how aggressive these two were who were doing it.
'Then a woman said to the girl she had to stop or she was going to call the police but rather than calm the situation that was like a red rag to a bull.
'I was watching all this and the poor woman was being followed around the grass and attacked.
'I just couldn’t stand there and I was just angry no one else seemed to be doing anything.'
She explains she was headbutted and then punched, and now has a black eye.
In a second video, believed to have been shot before the initial upload, the woman appears to kick and lash out in a group of male friends.
It sparks a brawl between the men, who start punching each other and shouting.
Those behind the camera exclaim: 'This is mental, oh my God!'
A man in a red top approaches another and floors him with a punch, swinging at him again when he tries to get back up.
The filmers try to settle the men down, but to no avail.
The man whips off his red top and goes storming over to another part of the brawl, where the woman is standing over another person and appears to be lashing out.
It is not clear who the victim was.
The videos first appeared on Coleraine Freshers' Facebook page, with the comments: 'With all the good weather being about, it brings out the smickeritos and the smickeritas into Botanic Gardens... All because she missed signing on the bru!'
A 17-year-old female has been arrested and charged with four counts of assault. She will appear at youth court in Belfast on May 31.
A spokesman for Northern Ireland police said: 'A 17-year-old girl has been charged with four counts of common assault and is due to appear at Belfast Youth Court on 31 May.
As is usual procedure the charges will be reviewed by the PPS.
'The charges follow an incident in Botanic Gardens area of south Belfast yesterday, Thursday May 4.
'A 25-year-old man arrested in connection with the same incident remains in custody at present.'
