The drama was filmed from a student's window in Mossley Hill, Liverpool after an angry row broke out in a university accommodation car park.

The Arriva 699 driver, dressed in a blue shirt uniform, can be seen on top of the orange-coloured cyclist before he grabbed him in a headlock, the Liverpool Echo reports.
As the pair wrestle to the floor, the driver shouts "do you want me to let go?" numerous times and "are you going to pack it in?" as the cyclist attempts to free himself.

The altercation took place in February and was shared on The Tab website.
An Arriva spokesman said the depot were aware of the incident.
He said the driver was attempting to restrain the cyclist after he threw his bike at the bus.
The pair continued to row before the cyclist rode off
The footage, which has been posted on YouTube, lasts for almost a minute in which time cars have begun to queue behind the bus to get into the car park.
After the scuffle the bus driver staggers to his feet, but the pair continue to exchange words which are inaudible on the video, before the cyclist picks up his bike and the driver gets back on to his bus.
The two then go their separate ways.
