A lorry driver claims to have spotted a large black cat walking along a main road through the Suffolk countryside.
Mr Emery believes he saw a black panther
Driver Martin Emery said he saw an animal five feet long and four feet high alongside his vehicle at Linstead Parva, Halesworth.
He said he believes it was a panther and also noticed a paw print nearby.
Peter Mortimer, chairman of Metfield parish council, said people in the area should exercise caution about approaching unknown animals.
Mr Mortimer told BBC Radio Suffolk he was keeping an open mind, given that other local people have also claimed to have seen a "big cat" in the area.
He suggested caution be taken around any unfamiliar creatures.
"It sounds as though it could be dangerous," he said.
According to the British Big Cats Society, certain areas of the country have seen a rise in sightings.
Among the most common sightings are the black panther, the puma and the lynx.
The society has set up a website to report sightings.
