A teenager received serious injuries after being 'robbed and pushed into a river' in Dorchester. 

Dorset Police received a report that the victim – a teenage boy – was reportedly assaulted and their blue backpack was taken by two other teenage boys outside the Co-Op store in Trinity Street.

It is reported that a man attempted to intervene before the three boys left the area.

The victim and the two teenagers then went to Frome Terrace where the victim was allegedly assaulted and pushed into the river.

It is further reported that a man who intervened near the river was also assaulted and sustained minor injuries.

The victim – who required hospital treatment for serious head and facial injuries – and the reported offenders are known to each other.

Following enquiries, a teenage boy from Weymouth was arrested on suspicion of inflicting grievous bodily harm, assault and robbery. He has been released on police bail as detectives continue their investigation.

Detectives are appealing for witnesses or anyone with information to come forward as they investigate. 

The incident took place on this date between 6.30pm and 7pm on Wednesday, July 31 and Dorset Police have only just released the information as part of their appeal. 

Detective Constable Mia-Isabella Bowditch, of Dorset County CID, said: “This was a nasty incident and we are conducting a number of enquiries to ascertain the full circumstances of how it occurred.

“I am keen to hear from any witnesses or anyone with information that could assist our investigation, particularly the man who attempted to intervene outside the Co-Op.

“I would also urge any motorists who were travelling in the areas of Trinity Street and Frome Terrace on the evening of Wednesday 31 July 2024 to please check their dashcam footage to see if they have captured anything of relevance.”
