An electrician is holding it up for the camera after he found it dead in a bush on a housing estate in Hackney Downs, east London.
His colleague Tony Smith took the photo and he claims the rat was four feet long and was bigger than his cat and Jack Russell dog.
“We were going to stick it in the bin,” said Tony. “But before we did we thought we better take a picture… people won’t believe it’s real.”
They say the rat was found near a children’s playground which backs onto a railway track.
Pest controllers found a rat the size of a small child yards from a kids’ play area on a housing estate in east London.
Gas engineer Tony Smith, 46, spotted the four foot long rat while working at a block of flats Hackney Downs.
The giant rat, which weighed almost two stone, was spotted lying in a bush next to a popular children’s playground.
The rodent, which was found dead, was discovered near to the play area which backs onto a railway track on Thursday.
Mr Smith snapped a picture of the rat being held by electrician friend James Green, 46, to the glee and disgust of his friends.
He said: “This is the largest rat I’ve ever seen in my entire life.
“I’ve got a cat and a Jack Russell and it was bigger than both of those put together.
