A YOUNG yoga instructor was discovered dead in a bathtub at the Ritz hotel with more than 30 stab wounds as police look for a phone with important evidence.

Shortly after 10 p.m. on Thursday, the body of 23-year-old Chow Wai-yin, popularly known as Aqua Chow, was discovered in a hotel room at The Ritz Carlton in Hong Kong.

Two hours after her ex-boyfriend, 28, presented authorities with the key to the hotel room at the Wong Tai Sin police station with the help of his attorney, they made the find.

He’s still being held in detention after being detained on murder allegations.

Officers found Chow’s belongings at the scene – but her phone has not been located.

A source told the South China Morning Post that it was probable that her phone was thrown away because it had crucial text communications between the two.

Given that the knife was purchased before the suspect booked into the hotel on Wednesday, detectives think the murder was planned.

“The inquiry reveals the individual had changed his clothes before he left the hotel before daybreak on Thursday,” said Superintendent Gar Kam-lam.

According to him, police discovered blood and evidence of fighting in the hotel room.

He claimed that she had been discovered with her head buried in water and in a bathtub full of blood.

A knife allegedly used in the stabbing spree, according to the head cop, was discovered in the bathtub.

“A forensic pathologist’s initial investigation reveals that the woman sustained more than 30 knife wounds to the limbs and her body in the front and rear,” he said.

According to him, Chow may have died from eight stab wounds to the throat and left side of her chest.

Chow might have been murdered before being placed in the bathtub, according to a source.

When her body was discovered, she was dressed and wearing shoes.

According to the source, “Blood was found on the floor, walls, bed, and nearly everywhere else in the room.”

According to reports, Chow was scheduled to travel to the US early on Thursday.

When the yoga instructor’s mother was unable to reach her and realised she had not boarded the flight, she reported her missing at around 1pm on Thursday.

Chow was seen leaving her apartment, where she lived alone, with her ex-boyfriend at around 4 p.m. on Wednesday, according to surveillance footage.

He was reportedly detained the previous year on accusations of threatening Chow before their breakup in December.

Around 4am on Friday, police searched a Mercedes-Benz in front of the detained suspect as he was brought to a public housing estate’s parking lot.
