A fire which destroyed a mansion formerly owned by Led Zeppelin guitarist Jimmy Page and occultist Aleister Crowley was not started intentionally, investigators say.

The blaze broke out at Boleskine House on the eastern bank of Loch Ness at around 1.40pm on December 23.

Around 60% of the B-listed mansion was destroyed in the fire, which took hours to bring under control.

Investigators are confident the fire was not suspicious but have been unable to establish its cause.

Crowley, who became infamous for his books on the occult, lived at Boleskine House between 1899 and 1913.

Former Led Zeppelin guitarist and Crowley memorabilia-collector Jimmy Page bought Boleskine House in 1970 but spent less than six weeks there before selling the mansion in 1992.

It has since been used as a private residence and a guest house and was put up for sale in 2009 for £176,000.
