A “shop worker” was punched in the face when he tried to stop a thief.

Hertfordshire Constabulary are investigating a theft and assault at Tesco Express in Katherine Place, Abbots Langley, just after 7.45pm yesterday.

A group of people were asked to leave the shop before a girl stole a bottle of Prosecco.

A man in his 20s was then punched in the jaw by another member of the group when he challenged the girl.

A witness on Facebook said the victim worked at the shop.

No arrests have been made.
