The detective leading the investigation into the murder of PC Gordon Semple has appealed for help to trace a man who called at the Southwark Street flat where the police officer's remains were found.
49-year-old Stefano Brizzi of the Peabody Southwark Street Estate who was charged with murder on Saturday, appeared in custody via virtual court at Bromley Magistrates' Court on Monday.
He was remanded in custody to appear on Wednesday at the Old Bailey.
Detectives are now satisfied that the human remains found at the flat in Southwark Street are those of PC Gordon Semple, who was reported missing on Friday 1 April.
Detective Chief Inspector Cliff Lyons, from the Homicide and Major Crime Command, who is leading the investigation into Gordon's murder, said:
"I am keen to trace a man who went to Brizzi's flat in Southwark Street on Friday 1 April at about 3pm. He was there for only one minute, and did not go inside, but it is incredibly important that we speak to him.
"If you are that man please come forward and call us on 020 8721 4961. I will treat what you tell me with sensitivity and confidentiality – please get in touch with us I need to talk to you."
