British authorities say a man has been convicted of perverting the course of justice after faking security camera footage to avoid a speeding fine.

Police and prosecutors say a courtesy car lent to 45-year-old Roger Moore was filmed speeding through the English coastal city of Plymouth on Feb. 22, 2011.

Moore claimed someone else was driving the car and submitted footage from his home security system purporting to show that he had returned home well before the incident.

But police said the shadows seen in the film were too short for February. A forensic examination by police computer experts showed that the film had actually been shot five months later.

Moore received a suspended sentence on Wednesday and was ordered to pay 2,000 pounds (roughly $3,150) in costs.
