A man who was jailed after his dog attacked five police officers has been cleared - after successfully arguing that police were to blame.
Symieon Robinson-Pierre's pit bull bit officers in Stratford in March 2012. A local resident described the scene as "the most horrific he had ever witnessed".
Robinson-Pierre was given a 22 month jail term after being convicted of having a dog dangerously out of control in a public place.
But the Court of Appeal overturned the conviction after he successfully argued that the dog's escape into a public place was the fault of the police - not his.
The police had forced entry into his house to execute a search warrant, and he claimed that was why the dog escaped.
Jurors had heard that Mr Robinson-Pierre had told officers after being arrested: "It's not the dog's fault. You should have knocked. I would have let you in."
