Three young men set upon the trainee hairdresser as she walked back home on May 20.

Terrified Jenna, 17, stood helplessly as one of the thugs knocked her to the floor with a single punch.

As she lay unconscious the man battered her with kicks to her face and body - leaving her with a broken nose and two chipped teeth.

The horrific incident in Hemel Hempstead, Herts, was captured on CCTV.

Police are now searching for the three thugs who left Jenna lying in a pool of blood in the road.

Jenna's father, Carl Burns, today appealed for information about the 'cowardly' thugs who attacked his 'beautiful daughter'.

He said: 'She has been very shaken up by the attack and won't leave the house on her own. I have been driving her everywhere.

'She is very nervous and in complete shock. Jenna was with a friend and had popped into town to see if any of their friends were out.

'They didn't meet anyone so started walking back. Jenna remembers seeing three young guys coming towards her on bicycles.

'They started verbally abusing her and the next thing she remembers is waking up in the ambulance.

'The first punch knocked her unconscious and then she was kicked as she lay on the road.

'My beautiful daughter was left her lying in the middle of the road in a pool of blood, she could have been run over. I am eternally grateful to the people who helped her.

'I can't understand what sort of cowardly person would do this to a young girl.' Read More
