A Swedish court has sentenced a doctor to 10 years in prison for abducting a woman and locking her in a homemade bunker, but acquitted him of charges of aggravated rape.

In a unanimous verdict, Stockholm District Court said Martin Trenneborg meticulously planned the abduction over a long period of time and subjected the victim to serious risk by sedating her and keeping her locked up in a soundproof bunker for almost a week.

The 38-year-old doctor, who claimed he was suffering a mental disorder at the time, was ordered to pay 180,000 kronor in damages to the woman.

The court said it found insufficient evidence that Trenneborg subjected the victim to sexual intercourse when she was sedated.

Trenneborg had admitted keeping the woman locked in the bunker - built inside a machine shed next to his home - but denied having kidnapped or raped her.

The court said it based its verdict on the victim's description of what happened and extensive documentary evidence, and said that it found no mitigating circumstances.

It described the doctor's mental disorder as "not serious".
