A Hong Kong jury has watched chilling video footage of a British banker allegedly torturing an Indonesian woman he is accused of murdering.
The footage also appears to show Rurik Jutting then talking for hours about how he repeatedly raped the woman and then killed her without feeling any guilt or emotion.
The video was shown on the second day of Jutting's trial for the murders of Sumarti Ningsih, 23, and Seneng Mujiasih, 26, whose bodies were found in his apartment near the city's red light district in 2014.
Jurors were played about 20 minutes of video in which Jutting apparently tortures Ms Sumarti. The media and public could not view the footage, but heard the audio.
At one point, 31-year-old Jutting can be heard saying: "If you scream I will punish you. Understand?"
This is followed by the sound of smacking and slapping, and later the sound of a woman whimpering. Jutting then tells her not to cry.
Later, both jurors and the public gallery were shown hours of iPhone video in which Jutting, wearing no clothes, delivers an extended rambling monologue to the camera.
"My name is Rurik Jutting. About five minutes ago I just killed, murdered, this woman here," he says into the camera, moving it to show her body in his bathroom shower.
He says on camera he held the woman captive and raped her repeatedly, and he discusses how he felt no guilt or emotion after the killing.
The defendant also says on the video he has "always had dark fantasies" involving rape, torture and murder.
Jutting, who worked for Bank of America-Merrill Lynch in structured equity finance and trading, said he had earned more than one million dollars over the previous two years but had spent most of it on drugs and prostitutes.
He watched the court proceedings from the glass-screened dock, showing no expression.
Ms Sumarti had been in Hong Kong earlier as a foreign maid but had returned on a tourist visa. Ms Seneng was officially on a foreign domestic worker visa but was working in a bar when she met Jutting.
Both women went to his apartment after Jutting offered them money for sex. Prosecutors said he killed both women by slitting their throats.
Jutting has pleaded not guilty to murder, with prosecutors rejecting his attempt to plead guilty to the lesser charge of manslaughter. If convicted, he faces life in prison.
At one point in the video, he holds up to the camera a small plastic bag apparently containing cocaine and a rolled up Hong Kong 10 dollar bill. He is seen snorting the drug several times in the videos, which were filmed over six days.
The last clip shown was apparently filmed after he killed Ms Seneng.
"I imagine this may be my last video, this just happened," he says in one, and then pointing the camera down to the floor, although it is too dark to see anything.
"I have killed two. The first one I tortured. There will be no redemption for me, but they are dancing with angels," he said.
The trial is scheduled to run for three weeks.
The case has shocked people in the Asian financial hub, which has a reputation for being safe but also significant inequality. It has also highlighted the decadent lifestyles of some members of the former British colony's expatriate elite.
