12 Year Old Boy Attacked In Boscombe
A 12-year-old boy has been attacked by a man in Boscombe - who accused him of throwing bangers at his car.
Officers are now appealing for witnesses and anyone with information to come forward after the assault along Cleveland Road between 5.05pm and 5.15pm on Monday 16 July 2012.
The victim, a 12-year-old boy from Bournemouth, was walking his dog together with his friend over Cleveland Road bridge toward St Clement's Road. The victim's friend was playing with and throwing small white snap bangers onto the floor when a turquoise coloured vehicle drove past and stopped.
Police Constable Dan Gadsden, of Bournemouth police, said:
"I understand that the front seat passenger stepped out of the car and accused the two boys of throwing the bangers at the vehicle.
"The victim's friend ran off - with the man chasing him in the direction of St Clement's Road.
"A short while later the offender returned and pushed the victim against a fence and then threw him to the ground."
The boy sustained grazes to his elbow and knee.
The offender then returned to the car which drove off turning right into Windham Road heading toward Ashley Road.
The vehicle has been described as small, with two doors and turquoise in colour.
PC Gadsden continued:
"I would urge anyone who witnessed this assault, saw the vehicle at this location, or has any information about the person responsible, to contact police as soon as possible."
Witnesses and anyone with information should call Dorset Police in confidence on 101 quoting incident number 16:354. Alternatively, call the free and anonymous Crimestoppers line on 0800 555 111 where mobile phone tariffs may apply.
