A biker's been injured by a piece of rubble - thrown at him along a major road in Poole.

The 56 year old from Blandford was riding a motor-trike westbound along the Dorset Way, near St Edward's School, just after six P-M last Saturday ... when he was hit by a 'fist-sized piece of brick', which left him with a cut to his chest.

Police say whoever did it would have been around the subway that runs under the road - but it's not clear if the brick was thrown maliciously.
