The owner of an aggressive dog has allegedly verbally abused a woman, after she informed him of its actions and told him that it should be wearing a muzzle.

The owner also reportedly threatened to punch his victim, and smashed a glass bottle on the floor - near to where she was standing.

The incident took place at around 2.45pm on Friday September 9, in Stevenage's Fairlands Valley Park.

At that time, the victim had been walking her dog in the park, when they were approached by a brown bulldog.

When the dog became aggressive, the victim informed its owner of its actions.

She also told the owner that, due to the animal's behaviour, it should be wearing a muzzle.

The owner then allegedly became verbally abusive towards her.

He also reportedly smashed a glass bottle on the floor, near the victim, and threatened to punch her.

The dog owner then left the scene on foot.

The man is described as white in complexion and aged in his mid 20s.

He is also described as having been wearing a black coat and black trousers.

Hertfordshire police have described the incident as "frightening" and "completely unacceptable".
