A woman has been arrested for allegedly helping a suspect in the gruesome killing and dismemberment of model Abby Choi in Hong Kong.
The arrest of the 29-year-old woman in mainland China brings the total number of people allegedly involved in the case to seven.
Police said they suspect she assisted another suspect and then fled to mainland China.
She was handed over to Hong Kong authorities at Shenzhen Bay Port on Tuesday.
The grisly killing of Ms Choi, 28, has gripped many in Hong Kong and in mainland China because the semi-autonomous southern Chinese city has a very low level of violent crime.
Last week, her ex-husband, Alex Kwong, his father, Kwong Kau, and his brother, Anthony Kwong, were charged with murder after police found body remains in a house rented by the dad in a suburban area of Hong Kong near the border with mainland China.
Alex Kwong's mother, Jenny Li, faces one count of perverting the course of justice. All four were detained without bail.
Police also arrested two others accused of assisting other suspects in the case.
Ms Choi, who had more than 100,000 followers on Instagram, disappeared on February 21, according to a report filed later with police.
She had financial disputes involving tens of millions of Hong Kong dollars with her ex-husband and his family, police said earlier, adding that "some people" were unhappy with how Ms Choi handled her finances.
Last week, police refocused their search on a landfill site as they continued to search for body parts of the model.
Her dismembered legs were found in a fridge in a makeshift butcher's workshop, but her head, torso and hand were still missing.
Six days later, cops found Ms Choi's head and ribs in a large soup pot.
More than 100 officers wearing protective suits were seen using excavators and shovels to search for her hands and torso.
The search for her remaining body parts had been taking place at the North East New Territories Landfill in Ta Kwu Ling, Hong Kong, close to the border with mainland China.
Superintendent Alan Chung told reporters: "The suspects threw away several bags of important evidence in the morning of 22 February.
"There may be some human body parts or they could be the clothes and phone of the victim - or even the weapons."
Police also found the model’s identity card and credit cards in the ground floor flat, where her legs were found as well as “tools that are used to dismember human bodies", Superintendent Alan Chung said, "including meat grinders, chainsaws, long raincoats, gloves, and masks."
Her friend, Bernard Cheng, said the model was mum to four children aged between three and 10.
Mr Kwong is the Father to the two eldest children, who are in the care of their maternal grandmother.
Mr Cheng said: "I haven't imagined a person who's so good, so full of love, so innocent, a person who doesn't do anything bad will be killed like this.
"My heart is still heavy. I can't sleep well."
