A motorcyclist caught riding at 122 miles per hour with his 14-year-old son on the back of the bike has been sentenced to six months in prison.

Robert Bennett, 47, was caught by a police camera on his 1300cc Suzuki while riding on the A361 North Devon link road.

The judge said: "The lack of responsibility is unbelievable. This is so dangerous that the court cannot avoid a custodial sentence, to send a message out."
