GHOSTLY goings-on at Croxteth Hall are being investigated by city bosses.
They have been left spooked by CCTV footage which appears to have captured an apparition making its way through the grounds.
Experts drafted in to view the footage say they are stumped by the image of the ghoulish figure, which can be seen bathed in a luminous white glow.
They say the short clip could prove to be some of the most important evidence of paranormal sightings ever unearthed.
City bosses investigating the sighting say there is a possibility it could be the ghost of the 7th Earl of Sefton, Hugh William Osbert Molyneux, who lived at the hall until he died, childless, in 1972.
Another contender is the 2nd Earl of Sefton, William Philip Molyneux, a prolific gambler and friend of the Prince Regent.
He laid the foundation stone for Aintree Racecourse, under which he placed a cask of sovereign coins, in 1829.
Local legend has it he stalks the grounds of the hall around Grand National time.
Former Most Haunted ghost hunter and TV presenter Jason Karl has been drafted in to examine the footage.
He said: ?This is very intriguing. Video footage of phantoms is very rare and if this stands up to scrutiny it could be a very important piece of spectral evidence for the worldwide community of paranormal enthusiasts.?
Council environment portfolio holder Cllr Berni Turner said she was keeping an open mind about the footage.
She added: ?I?m a huge believer in the paranormal and think this footage is really interesting.
?It?s great to think that we may have ghosts walking around these beautiful grounds.?
Generations of the Molyneux family, the Earls of Sefton, lived at Croxteth Hall from the sixteenth century.
It was bequeathed to the City of Liverpool by the 7th and last Earl of Sefton, Hugh William Osbert Molyneux, and his wife, n?e Josephine Gwynne, who was the last member of the Molyneux family to live at Croxteth and died in 1980.
