This is the astonishing moment two chimpanzees with alopecia sparked a mass brawl between a group of apes at a zoo.

The video, filmed yesterday at Twycross Zoo at Atherstone, England, shows the two angry chimps, who are completely bald, chasing each other and fighting in their enclosure.

The pair, who are believed to be father and son, begin their scrap by chasing one another and baring their teeth while screeching before the entire group of chimps become involved.

Speaking about the ferocity of the fight the person who filmed the scrap later wrote online: 'A few scratches and some minor wounds and probably a few more scars.'

They are not the first chimpanzees in captivity to suffer from alopecia.

Scientists believe as chimpanzees as so similar to humans it could be caused by factors such as stress or trauma, which can induce alopecia in humans.

Monkeys and apes have also been known to develop an abnormal pattern of behavior in which they pluck their hair - or even pluck out each other's hair.

However, alopecia in captive monkeys is most often attributed to stress.

MailOnline has contacted Twycross Zoo for comment.
