An ‘out of control’ dog has died in police custody after it was seized by officers in Gladstone Park.

The dog was impounded by officers after it bit an assistant dog and shook it around ‘like a rag doll’, according to a witness to the attack.

The man, who asked want to be named, said he was walking his dog at the park in Dollis Hill.

He said: “The dog attacked another small dog like a rag-doll it was luckily not a child.

“My little dog could have been next.”

It is not known what injuries the attacked dog suffered.

A spokesman for Brent Police said the dog died from breathing difficulties.

A 22-year-old woman was arrested and subsequently cautioned for being the owner of a dog which was dangerously out of control.
