Captures and remains
A Eurasian lynx was shot in summer 1991 near Norwich, Norfolk. It had killed around 15 sheep within two weeks. The story was only reported in 2003, and the lynx is apparently now in the possession of a collector in Suffolk (as taxidermy). For many years this incident was considered to have been a hoax, particularly by the hunting community, But in March 2006 a police report confirmed that the case was true. It was probably an escapee from a facility in the area that bred animals, including Eurasian lynxes.[7] Another lynx and a puma have been captured alive.[8]
[edit] Video and photographic evidence
In June 2006 a large black cat was recorded in the countryside of Banff, Aberdeenshire. Footage of the cat was broadcast by the BBC on the 24th May 2007.[9]
In July 2009, photographs and video footage of a large black cat were taken by an off-duty Ministry of Defence Police officer. The animal was walking along a railway line in Helensburgh, Argyll. Large cats, either black or tan, have been reported in the area before.[10
