COPENHAGEN, Sept. 14 (Xinhua) -- The appeal trial of Danish submariner Peter Madsen, who is seeking a reduced sentence for killing the Swedish journalist Kim Wall, was postponed here on Friday as a judge in the Eastern High Court fell ill during the hearing.

The lay judge, one of two serving along with three judges, lost consciousness after the prosecutor began presenting his final arguments and eventually left the court on a stretcher.

The judge regained consciousness in the ambulance, according to the court.

Madsen, 47, was on April 25 sentenced to life in prison for the premeditated murder of Wall on his submarine last August.

In the three-day hearing, Madsen did not appeal against his murder conviction, but sought a time-limited rather than open-ended prison sentence.

The court had been due to present its verdict on Madsen's sentence later Friday. It is not yet known when the case will proceed again.
