People in north-west England are being warned not to approach a porcupine which burrowed out of a farm visitors centre and is now on the loose, BBC Online reports.
Twinkle, a 0.9 metre ( 3 foot) long female, escaped from her enclosure at Eden Ostrich World near Penrith on Saturday, prompting warnings because her detachable, poison-filled quills can become embedded in skin.
Jim Peet, from the centre, was quoted as saying that Twinkle was normally "cool" but was classed as a dangerous wild animal because of her spiky appearance.
"She could make a real mess of someone's garden and she should not be approached as her quills contain poison and she could become flustered if backed into a corner," he added.
Twinkle's disappearance came after some British newspapers said police had received reports of a tiger on the loose in Yorkshire, northern England.
