It occurred at around 1.15am on Sunday 30 June 2013, as a 20-year-old local woman walked along St Andrew’s Walk.
She was approached from behind and hit once in the face, causing a swollen lip.
PC Linsey Moore, of Harrogate Safer Neighbourhood Team, said:
Thankfully the victim Wass no seriously hurt. However, she was left shaken by the assault.
As the incident only lasted for a short time and the woman was taken by surprise, she was unable to get a description of the person who hit her.
If you have any information that could help to identify the assailant, I ask that contact the police as soon as possible.
