Police continue to appeal for information surrounding the murder of 39-year-old Martin Thomas in Roehampton, south west London, last month, particularly information that would assist detectives in identifying three people seen in the area prior to the incident.
Detective Chief Inspector Charlie King, from the Homicide and Major Crime Command, said earlier:
At this early stage we are keeping an open mind about any possible motive.
Members of the public have already provided us with accounts of three young men seen loitering in the area prior to the incident. I am directly appealing to these young men to come forward and speak us.
I am also urging anyone who may have more information regarding this incident to contact us.
