London’s Metropolitan Police have launched a manhunt for the person who stabbed to death a 27-year-old Hong Kong-Thai woman in her expensive property on the edge of Hyde Park in the capital.

The body of Kamonnan Thiamphanit was discovered by police after they forced entry to her property on Monday.

The police were contacted on Sunday by the victim’s friends who were concerned about her welfare. Officers entered the property 13 hours later.

Neighbours told Daily Mail online that they heard high-pitched screams and then a worrying silence hours before her body was found. It is thought that Kamonnan may have known her attacker, as the five-storey building has a video entry system on the front door and there was no sign of forced entry before police officers entered on Monday morning.

Detective Chief Inspector Adam Clifton, who is leading the investigation, said that his team continues to work tirelessly to piece together the events that led up to the murder. He appealed to anyone who has information that could assist his investigation, “no matter how insignificant you think that may be”, to come forward and to speak to the investigators.

The flat near Hyde Park was still sealed off by police yesterday as the murder investigation entered a fourth day. Uniformed officers patrol the scene while several forensics vans remain parked outside as a scenes of crime teams continue to process the flat.
