In the video Rurik Jutting describes how he raped and tortured a woman for three days before killing her
Jurors in Hong Kong have been shown a chilling video of former British banker Rurik Jutting describing how he raped and tortured an Indonesian woman for three days before killing her.
In the footage, he stands, shirtless, in his apartment, recording himself on his mobile phone.
"My name is Rurik Jutting. About five minutes ago I just killed, murdered, this woman here," he tells the camera.
The camera pans down to show the body of 23-year-old Sumarti Ningsih, lying face down on the bathroom floor.
He holds up his hand, which appears to be shaking.
"It's Monday night. I've held her captive since early Saturday, I've raped her repeatedly, I tortured her, tortured her badly," he said.
He goes on to talk about using cocaine and prostitutes in Hong Kong and the Philippines.
In another video, Jutting, 31, can be heard apparently torturing Ms Ningsih before her death.
"If you scream I will punish you. Understand?" he says.
The sound of smacking and slapping follows.
The former securities trader watched the videos from the glass-screened dock in court, looking down at times at a transcript of the video in front of him.
He admits killing Ms Ningsih and a second Indonesian woman, 26-year-old Seneng Mujiasih, in 2014, but denies murder on the grounds of diminished responsibility.
He has pleaded guilty to a further charge over the unlawful burial of Ms Ningsih's body, which he wrapped in plastic sheets and concealed inside a suitcase on his balcony.
His second victim's body was found in a pool of blood on his living room floor with her throat cut.
Before going out to meet Ms Mujiasih, the prosecution says he bought a small blowtorch, plastic ties and a hammer, and hid two knives under the sofa cushions.
Both sides agree that Jutting met her in a bar and offered her money for sex, before bringing her back to his apartment.
She is said to have started screaming when she saw a rope gag near the sofa, at which point Jutting grabbed and killer her.
In one of his police interviews, he told officers he had gone out that evening "hunting for prey" and that she was his prey.
He called police to the apartment himself after the second killing, and claims to have started hallucinating after using cocaine.
Traces of the drug were found in more than two dozen small plastic bags in his apartment, according to the prosecution.
Jutting was born in Surrey and graduated from Cambridge University before moving to Hong Kong to work for Bank of America Merrill Lynch in 2013.
He has been evaluated fit to stand trial after psychiatric tests, and is currently being held at a maximum security prison.
If convicted he faces a mandatory life sentence.
