A 20-year-old Orangeville man has been arrested and charged with second-degree murder after a man was found dead in a south London hotel on Sunday night.

James McCullough is facing one count of second-degree murder and one count of committing an indignity to a human body.

London police were called to the Travelodge Hotel at 800 Exeter Road on Sunday around 8 p.m.

Officers say they discovered the body of the dead man upon arrival at the third-floor room and took the other man into custody.

Police believe the two males knew each other and say they are treating the investigation as a homicide.

Officials have not released the identity of the victim or the cause of death.

London police Const. Ken Steeves says the man's body has been transported to London Health Sciences Centre for an autopsy, which is expected to be completed by Tuesday.

The death marks the third homicide in London this year.
