A man grabbed a woman’s shoulder and assaulted her in an alleyway in Gosport.

The incident happened behind Chantry Road on Tuesday morning.
The woman was not hurt.
She described the man as being between 5ft 9ins and 6ft tall, and being quite muscular across the shoulders.
The lower half of his face was covered, but had dark brown eyes and freckles just below the eyes.
He was also wearing a black hooded top with the hood up and blue jeans which were faded on the back.
