Police have released shocking photographs of a woman knocked unconscious in an unprovoked assault.
Sasha Jenkins, 28, was walking with a friend in Staple Hill, Bristol, at 12.45am on July 5, after leaving the White Swan pub in Downend, Bristol.
Two men walked towards the carer - with one suddenly punching her to the ground as he passed her.
She was rushed to Southmead Hospital with severe facial injuries and later underwent a "painful" operation.
Detective Constable Clare Chipping, of Avon and Somerset Police, said the "horrific" pictures had been released in a bid to identify her attacker.
"Sasha wants to release these photos of her before and after the attack to show the horrific nature of the injuries she suffered," DC Chipping said.
"She's had to endure a painful operation and will need further treatment in the days and weeks ahead.
"At the moment she's taking time off from her job as a carer because she's had to wear a protective mask as part of her treatment.
"We don't have a description of the two men who approached Sasha other than that they were young men.
"We have carried out a number of inquiries already and now want to issue an appeal for anyone who witnessed this incident to come forward.
"I am convinced there will be people who know who is responsible and I would urge them to put aside any misguided loyalty and contact us."
A 31-year-old man has been arrested in connection with the incident and is on bail until August 24, she added.
Anyone with information is asked to contact the force on 101.
