Police investigating the death of Russian national Nikolay Glushkov are seeking to trace a black van driver, after the retired financial director was found dead at his New Malden home.
Detectives have released CCTV footage and images of a black Volkswagen van seen in and around Clarence Avenue in New Malden between 7.30pm and 10.30pm on Sunday, March 11.
Detectives are keen to identify the van and driver, who they believe could have information that may help with their enquiries.
A murder investigation was launched on March 16 following a post-mortem examination, which gave the cause of death as compression to the neck.
Detectives have so far obtained a total of 286 witness statements, 159 witness questionnaires and seized 1,086 exhibits.
No arrests have been made and enquiries continue.
Anyone with information about the van or driver can call police in confidence on 0800 789 321 or contact Crimestoppers anonymously on 0800 555 111.
