A dog savagely attacked a family pet in Twickenham riverside.

"Billy" a 15-year-old cross between a shar pei and a Chinese crested, was left with several bite wounds after the mauling  and police hope releasing this image will help their investigation.

According to officers a ginger dog, walking without a lead, jumped on Billy and repeatedly bit him.

The attack happened on August 17 at about 3.30pm.

The owner of the suspect dog was a white male in his 60s, with grey hair.
