A dangerous driver has been jailed for nearly three years after he dragged a police officer along a dual carriageway.
Motorist Marlon Joao was pulled over by PC Joanna Halewood for driving the wrong way down the A road - and blamed his Sat Nav.
But as PC Halewood reached inside the Vauxhall Insignia to try to remove its keys when she noticed Joao was about to flee, he grabbed hold of her arm and raced off.
