"I told the policeman I thought dogs were trained..."

Her neighbour, who claimed to witness the attack, told Shirley what she had seen. "She said she saw my cat walking around the corner and a big dog, different to the one I saw, followed her.

"My cat was looking back at this dog and didn’t know whether to run.

"The dog literally attacked, and she said it was horrific to watch. The policeman was not far behind and the dog wasn’t on a lead.

"He dropped the cat when the policeman called him back."

 The lying cops didn't tell the distraught owner the full story:

It was 6.30am when an officer knocked on her door.

"He asked me whether I owned a black and white cat and that he was sorry but that his colleague's dog attacked it.

"I was horrified and very quiet because I think I was in shock. They said there was a bit of blood on its tail so they brought it to the vets."

In fact, it had multiple bite wounds and collapsed lungs. Injuries that should have been obviously far more serious than 'a bit of blood on its tail'.

She has made an official complaint to the Met Police after allegedly being told by an officer that the dog "didn't like cats".

What the hell is a dog that's known to be a danger to other animals doing being unleashed in an urban area crawling with other people's pets? Why is it even still a police dog?

Spangle’s vet bills came to £8,000, which Shirley said the police are thankfully covering.

No, Shirley, you're covering them. You, and every other taxpayer. Where do you think the police get the money in the first place?

A police spokesman said the matter was being investigated and alleged dog bits (sic) are taken "very seriously".

The dog should be destroyed, and the handler reduced to counting knives in the evidence locker for the next ten years.
