Police are investigating after a woman was knocked over and bitten by a dog in South Mimms.

Officers today (Wednesday) issued an information appeal after the victim, in her 40s, was attacked.

It happened in fields off Brookside at around 9am on Saturday, November 8.

The woman, from Potters Bar, was bitten in the arm and hands.

A man who was walking the Staffordshire Bull Terrier-type animal rushed over and restrained it.

He asked if the victim was alright, but walked away when she replied: “No.”

She needed medical treatment for her wounds.

The dog is described as being light grey and believed to be youngish.

The man is described as white, in his late 50s and very slim.

He is believed to be around 5ft 8ins, and he had grey or white hair and a moustache.

He was wearing a khaki-coloured parka and pale jeans.

PC Gareth Clifford, investigating, said: “The woman was fortunate not to be more seriously injured and, as such, we would like to identify the dog and who it was with as soon as possible.

“It’s believed there may have been a man walking a Collie-type dog in the field just prior to the incident and he may have witnessed what happened or have other information that could prove useful to the investigation.

“If anyone believes they saw what happened or knows who the dog may belong to, please contact me.”

Anyone with any information is asked to contact PC Clifford via Hertfordshire Constabulary’s non-emergency number 101, quoting crime reference J1/14/3571.
