Russian police found a modified Bentley fitted with tank tracks.

The GT Coupe was discovered during a raid on a garage workshop in St Petersburg, Russia, by immigration police on July 30, as part of an operation targeting illegal workers.

Dramatic footage shows the unusual hybrid vehicle parked among weeds and bushes outside the garage.

Officers uncovered 67 hybrid or heavily modified vehicles on the site, many with illegal registration or unsafe structural changes.

A police spokesman said: 'Given the nature of the site, special attention was paid to vehicles.'

The Bentley appears to be a development of the earlier 'Ultratank' built by Russian auto enthusiast Konstantin Zarutskiy for his YouTube channel AcademeG.

His original prototype, with higher tracks, reached speeds of up to 81 mph, far below the Bentley's standard 200 mph but fast for a tracked vehicle.

Authorities also detained nine workers who were allegedly employed illegally and now face deportation.
