An investigation has been launched after a shocking video emerged showing 14-year-old girls being forced to their knees and beaten by teeange female bullies for 'giving dirty looks'.

The pair were punched and humiliated by the older girls, who order them to 'say sorry', before their bags were emptied and thrown on the road in the Northfield area of Birmingham, West Midlands.

Grainy footage of the attack, believed to have happened on Saturday, has been widely circulated online and viewed six million times after members of the laughing crowd began filming the assault.

A pair of 14-year-old girls were forced to their needs and made to 'say sorry' after apparently giving older girls a 'dirty look'

It is thought to have started after the girls gave 'a dirty look' to one of the teenagers, who demanded they get on their knees and apologise.

She repeatedly shouts: 'Get on your knees and say sorry', and tells her that when her friend accepts the apology she can get up, otherwise she will 'throw your bag in the road and beat you up'.

When the younger girl refuses she empties her bag in the road and then forces her to kneel in white paint as the 14-year-old replies 'sorry for giving you a dirty look'.

The older girl then hits the girl across the face with her empty handbag as she shouts 'don't laugh otherwise I'll hit you in the face - who do you think you are?'

She then throws the bag onto the dual carriageway before turning on the younger girl's friend and forcing her to do the same.

The other girl tries to desist giving into the teenager's demands and tells her friend to ring her grandmother while asking the older teen to get off.

She shoves her to the ground, hits her over the head with her bag and pins her to the ground screaming: 'What are you going to do? You're a little girl. What are you going to do?

'Are you going to say sorry? Who are you growling at? Say sorry for not getting on your knees.'

The humiliating assault was filmed by members of the crowd who laughed during the attack - said to have happened in the Northfield area of Birmingham, West Midlands

The young girl then agrees to get on her knees and apologise while the older girl rummages through her bag and starts removing the contents.

She later humiliates her by ordering her to take her shoes and socks off and then throws her trainers in the road.

A bottle of expensive perfume is also seen being smashed on the ground while one of the girls begs her friends to call her grandmother.

Detectives have already spoken to two of the group involved - including the male youth who filmed the incident - and plans are in place to arrest the two female offenders.

Inspector John Askew from Birmingham South Police, said: 'The response from members of the public, clearly disgusted by what they've seen online, has been overwhelming and we've had lots of people getting in touch to provide names of those responsible.

The older girl then climbs on top of her and tells her 'don't growl at me, what are you going to, you're a little girl, are you going to say sorry?'

She then makes her take her shoes and socks off before throwing her trainers in the road and smashing a bottle of perfume

'We have identified the two main suspects and plans are in place for one of the girls, a 16-year-old, to attend a police station for questioning later today.

'We understand the other main suspect is out of the country on holiday but we will speak to her upon her return.

'I would like to reassure everyone this is being treated very seriously and that the enquiry is progressing*under no circumstances should anyone take matters into their own hands as this could leave them liable to prosecution themselves.'

The unprovoked attack saw the girls, both aged 14, being forced to their knees to apologise for 'giving dirty looks' before one was shoved to the floor and assaulted; the victims' handbags were also thrown into the middle of a busy road.

DS Dean Gordon, of Birmingham Police, added: 'The violence shown against these two girls is completely unacceptable*we will not tolerate this kind of bullying and those involved will be brought to justice.'

Both of the girls were threatened to 'get on your knees and say sorry' as cars sped past a dual carriageway
