A violent, serial rapist from Tayside who spied on victims during a catalogue of crime was warned he could face a life sentence.
Lee Thomson, 48, attacked and raped three woman during an ordeal of abuse in Dundee and Perthshire that spanned 15 years.
Yesterday, a judge was told at the High Court in Edinburgh that Thomson continued to maintain his innocence after he was earlier convicted of 14 charges, including six rape offences, sexual assault and assault.
Thomson, formerly of Barnes Avenue in Dundee, attacked and raped his first victim at a house in Perth and Kinross.
He later raped the woman again at a hotel in Dundee and bit her on the body.
He earlier subjected the woman to a further assault when he pushed her to the ground, sat astride her and bit her on the head.
The woman was also punched on the head in one attack.
Thomson had monitored the woman’s movements and conversations through hidden audio and visual recording devices.
He also tracked the movements of a second woman and monitored her conversations through covert audio recording equipment at addresses in Dundee.
She was also subjected to rape attacks by Thomson at an address and hotels in Dundee.
Thomson attacked the woman on occasions when he violently shook her, grabbed her by the neck, pinned her down and punched her on the head.
He brutalised a third woman, who was also seized by the neck and was pushed, thrown, kicked, slapped on the head and subjected to a bodily examination.
Thomson also sexually assaulted the woman when she was sleeping and on a further occasion raped her at a house in Dundee when she was unconscious after using a ligature on her.
Solicitor advocate Chris Fyffe said Thomson had experienced feelings of paranoia and jealousy and for several months had abused cocaine heavily.
The offences began in March 2003 and ended in April 2018.
Lord Uist told Thomson that he would be detained in Grampian Prison for the preparation of a full-risk assessment report, which can lead to creation of an order for lifelong restriction.
Under such an order the court fixes a period of imprisonment the offender must serve, but any future release is in the hands of the parole authorities.
