Kanagusabi Ramathan, 75, was found dead at their home in Burges Road on Friday afternoon.
Paramedics say he had suffered a serious head injury, although a post-mortem has not yet been carried out.
Kanagusabi’s wife, Packiam, was arrested shortly after and has today been charged with his murder.
Lead investigator Chris Soole said: “While I’m confident we have charged the only suspect involved in this incident, I would still like to appeal to anyone who may have information that could help us piece together the chain of events that led to a man losing his life.
“In particular, I’d like to hear from anyone who had contact with the defendant or victim in the days and hours leading up to this event.”
Anyone with information should call the Met Police on 101 quoting CAD 4064/21 Sept.
