Biker Hit By Rubble In Poole
Police are trying to find out who threw rubble at a biker on a major road in Poole.
A fist sized piece of brick struck a man riding a motor tricycle on the chest on the Westbound carriageway of the Dorset Way, near St Edward's Comprehensive School, at around 6.10pm on Saturday 2nd June 2012.
The 56-year-old victim from the Blandford area was cut on his chest.
Police Constable Will Burnett, of Poole Police, said:
"This is an extremely dangerous incident and it's fortunate that the motorist involved did not sustain more serious injuries or lose control of his vehicle on this very busy road.
"It is not clear whether the rubble was thrown maliciously or recklessly, but it is important that anyone with any information about this incident should contact the police at the earliest possible opportunity.
"I understand that the perpetrators would have been in the vicinity of the subway that runs under the Dorset Way near the school. I'd also urge anyone who saw any suspicious activity in this area during Saturday evening to get in touch urgently."
Witnesses and anyone with information should call Dorset Police in confidence on 101.
