Police have appealed for witnesses after a pedestrian in his 70s died following a crash in Watford.

A sea of emergency services swarmed the A405 North Orbital Road junction with Bucknalls Lane after the collision involving a black Toyota Yaris on Friday evening.

Footage seen by the Watford Observer shows numerous police cars and ambulances around a taped-off stretch, with officers searching a nearby wooded area.

The pedestrian, a man in his 70s, died at the scene while the Yaris driver, a woman in her 20s, was not injured.

A Herts Police spokesperson confirmed the vehicle and driver both remained at the scene.

Sniffer dogs were deployed over initial concerns a second injured person was not accounted for, but that proved not to be the case, they added.

The huge emergency services response sparked speculation online of more than a collision – but that has now been confirmed not to be the case.
