A crash in Watford left a man trapped before the car roof was cut off and he was taken to hospital.

The collision involving a grey Vauxhall Corsa and a black Honda was in Hagden Lane, Watford, shortly before 6am on Saturday.

A picture shows the Corsa, with its roof sliced off and resting upside down on the bonnet, facing the Honda with a crumpled, front-right wheel.

What looks like one of the doors also appears to be resting on the back seat, with debris strewn across the road.

Herts Police said they were called to the two-car crash alongside the ambulance and fire services and road closures were installed.

One person was found trapped and suffering from neck and back pain, a Herts Fire and Rescue Service spokesperson said, before crews cut them out of the car.

The driver, a man in his 30s, was then taken to Watford General Hospital for further assessment of a back injury.

The injury is not believed to be severe and no one was arrested. The road reopened around three-and-a-half hours later.

Just a day later, a fire ripped through a commercial building in the same road. No one was injured and authorities believe it was started accidentally.

Multiple crews and Herts Police rushed to Hagden Lane shortly before 6am as locals were urged to keep their windows and doors shut.

The blaze was later confirmed to be at Lamberts London Ltd, a company that specialises in decorative metal finishing, plating and surface coating.
