A teenage girl sustained a cut to her thigh after she was attacked by a man in a park.

The victim was walking through Oxhey Park, Watford, at around 6.30pm yesterday when she was approached by a man who grabbed her arm.

He then used a small, sharp blade which cut her thigh before he ran off.

It is not known at this time exactly what was used to injure the teenager. 

The girl was not seriously injured.

Nothing was stolen during the attack.

The suspect is described as being aged between 30 and 40 years, of broad build, with short brown hair, clean shaven and spoke with a foreign accent.

He was wearing black trousers, a grey T-shirt and carrying a black rucksack.

Following the attack, police have increased patrols in the area.

PC Rebecca Robinson said: “Thankfully the victim was not seriously injured during the incident but has understandably been left shaken by what happened.

“I appreciate this incident may cause some concern in the community and I want to reassure people that we are increasing patrols in the area and carrying out enquiries to trace the person responsible. As part of this, I would like to hear from anyone who may have witnessed the incident or events leading up to it.

"Do you recall seeing a man in the area matching the description given? Any information, no matter how seemingly insignificant, could greatly assist our investigation.”
