Provincial police northwest of Toronto say they've charged a man with second-degree murder in the death of a 50-year-old man from Brampton, Ont.

Police say the incident happened in Mono, Ont., early Friday morning when a 27-year-old man allegedly assaulted the victim after an argument.

Investigators identified the victim as Taranjit Singh. The 27-year-old man is Anmol Saggu of Brampton, Ont.

Investigators say the accused has also been charged with assault and failure to comply with a probation order. Police say the man made his first court appearance on Saturday.

The mansion on the property, south of Highway 89 on Hurontario street, remained a crime scene Sunday afternoon. Three cars were parked on the property, including a white Mercedes and black Audi; though nobody was home, or was seen entering or leaving the home guarded by police. 

Police have not released the cause of Singh's death. A publication ban has been imposed on the case according to police.
