The victim – a Bournemouth man aged in his 20s – reported being punched in the face by two men.

The men walked away and the victim continued to walk toward Pokesdown. As he reached Sainsbury’s, he was grabbed from behind by his rucksack, before being repeatedly punched and kicked while on the floor.
