NASSAU, Bahamas (AP) — Bahamian police investigating the stabbing death of a retired doctor from Canada have arrested a suspect who likely will be charged with murder.

Geoffrey Harding, an 88-year-old former resident of British Columbia, was slain last week at his home on Long Island, a sparsely populated part of the Bahamas.

Assistant Commissioner Stephen Dean of the Royal Bahamas Police Force said authorities believe the 43-year-old suspect killed Harding during a robbery.

The name of the suspect was being withheld pending his arraignment, expected later this week. Dean said Tuesday the suspect had no relationship with Harding and was someone "known to police."

Canada's Foreign Affairs Department says Harding held U.K. citizenship though he had lived in Canada before retiring to the Bahamas.
