Police have released a CCTV image of a man they would like to talk to in relation to the attempted robbery of a dog in Kilburn.
Police are appealing for information following the incident in which a chihuahua was stolen from its owner.
The dog was stolen on Saturday September 20 last year, at around 1pm, outside The Alice House in Kilburn, by a man who ran off along Brondesbury Road.
The dog's owner then placed posters in the area asking for information and the safe return of her pet.
A man then contacted her on Friday October 3. He said he was in possession of the dog, agreeing to meet her in Tavistock Plaza, Harlesden.
At 10pm that day, a man turned up in possession of the dog, but became aggressive and asked for money, police said.
He threatened to kill the dog and shoot the owner.
The owner - who at this point had hold of the chihuahua - ran away and was chased into a nearby fast food outlet, where she was cornered and threatened again, with the man now demanding she handed over her phone.
The victim managed to escape after being pursued along Harlesden High Street, escaping in a vehicle.
Acting Sergeant Martin Redshaw, of Brent’s Queens Park Safer Neighbourhoods Team, said: "I am appealing for anyone who can assist in the identification of the man in the picture to contact me.
"This was a very distressing episode for the woman involved, so I am keen to find him as soon as possible."
Anyone who recognises the man or has information as to his identity is asked to call police on 101 quoting reference CRIS 1924349/14. Alternatively contact Crimestoppers on 0800 555 111 or vie the Crimestoppers website.
