A man phoned the emergency number for West Yorkshire Police to report that his girlfriend had let the cat eat his bacon and that he wanted to press charges.
The call starts with the man being asked: "What's your emergency?"
"Er...me girlfriend has let the cat eat my bacon," the man states.
The bewildered call operator asks him to repeat his claims before asking what he would like the police to do.
He simply replies: "I want to press charges."
The call handler keeps her cool and professionally asks whether he wants them to arrest his girlfriend or the cat.
And when the man replies both, she firmly tells him: "Sir, it's not an offence to let your cat eat your bacon. And we don't arrest cats."
He starts to protest and insists it's the girlfriend's fault for allowing the cat to do it. But when he is told it's not a 999 emergency, he finally concedes and ends the call.
'Which actor played Magnum?'
Tom Donahoe, who heads a team of 200 staff at the customer contact centre based in Wakefield, said: "Someone rang us at two in the morning to ask us who the actor was that played Magnum P.I.
"It was driving him mad, he was with his friends and couldn't think of the answer, so he rang the police."
He added: "The serious point is that, a lot of the time we're talking about a matter of seconds between us being able to get to a genuine emergency effectively and not being able to and therefore having people's lives put at risk."
