I would like to hear from anyone who lives in Platford Green, or the surrounding streets, who saw a man acting suspiciously in the area during Tuesday morning.
He may have been knocking on doors and trying to talk his way into peoples' houses. He is described as a white man, 6ft2ins tall, of heavy build but not muscular, wearing a navy pin stripe suit. If you saw him or spoke to him please get in touch with us.
We are keeping an open mind regarding the motivation behind this murder, but I am confident that the victim and the suspect were not known to each other.
Any witnesses are asked to contact the Incident Room and give us any information they may have on 020 7321 7228.
