The Beastwatch UK survey recorded 5,931 apparent sightings of big cats, 332 of wild boars and 3,389 of sharks since 2000 - with figures expected to rise.
(Seemingly exotic animals roaming free are becoming an increasingly common sight in the UK. These figures are expected to rise as people who thought it was cool to keep an exotic pet find they are good at escaping or just get fed up of them and chuck them out.)
