A mousetrap caught something bigger than bargained for when it managed to snare an unsuspecting snake.
The orange and white corn snake was spotted in Poplar, east London after it managed to get stuck by slithering into the trap.
A passer-by alerted the RSPCA on Saturday who freed the reptile.
The RSPCA’s Joe White, who attended, said: "The poor snake could barely move and was well and truly stuck in the mousetrap.
"The snake had an abrasion where he was stuck but his injuries do not seem to be too severe."
An owner could not be traced and the animal was taken to South Essex Wildlife Hospital for veterinary treatment.
"If we cannot trace an owner then the snake will be rehomed," the RSPCA said.
The charity said it was not clear whether the snake had escaped or if it had been abandoned.
