A rescue dog from leading pet charity Blue Cross is now fighting crime in London after the Metropolitan Police agreed to take him on after no one else would.

Dizzee was down on his luck because his sheer strength, energy and drive meant that he wasn't a suitable family pet and needed a working role.

He was also rejected by every police force that the Blue Cross team based in Burford, Oxfordshire, contacted. The team were concerned he would be "unemployed" forever.

Determined not to give up on the one-year-old German shepherd dog, who was becoming increasingly stressed in kennels, the team called the Metropolitan Police and persuaded them to give Dizzee a trial at its elite dog training school in Keston, Kent.

In less than eight months, Dizzee qualified as a general purpose police dog, graduating at a passing out parade in Keston in July this year and is now working to keep the streets of London safe.

He has wasted no time in making an impression and has already stopped a street robber in Ealing and help arrest someone indecently exposing themselves at a west London park.
