A young hero mom shielded her baby boy with her own body after a motorbike ridden by a suspected drink-driver ran into them as they got out of a van.

The 19-year-old and her 17-month-old son were knocked to the ground after they climbed out of a community service van. The rider had tried to cut between the vehicle and the kerb.

Police said the young mother managed to keep hold of her child and protected him with her body as they slammed into the roadway.

A police spokesman explained the bike hit the sliding door of the van, then the woman and child.

The bike then hit a wall and the rider, a 24-year-old man from Pembroke, was thrown off.

All three were taken to the King Edward VII Memorial Hospital after the collision.

The baby was found to be uninjured, but his mother suffered a knee injury.

The motorbike rider was treated for minor injuries to his wrist and shoulder, and later arrested on suspicion of drink-driving.

The incident happened on Parsons Road, Pembroke, near its junction with The Glebe Road, at about 10.20pm on Friday.

Police are investigating the incident and appealed for witnesses.
