POLICE have launched a hunt for a couple who pretended to need critical roadside assistance and then preceded to abduct the 'Good Samaritan' who stopped to help them.

The victim was driving along the A500 yesterday morning at 6am, near Nantwich, Cheshire when his car was flagged down by a young woman in visible distress.

She was standing beside the prone body of a young man, lying motionless in the gutter.

When the 29-year-old man went to give assistance the 'injured man' leapt to his feet brandishing a knife which he held to the driver's throat.

The couple bundled the man into his own car and forced him to drive onto the A548 to North Wales before dumping him and making off with his car.
