Montreal police are investigating a suspicious death in a sauna on St-Laurent Boulevard near St-Joseph Boulevard.

A man in his 40s was found dead late Friday afternoon, at about 4:45 p.m in a cubicle at Sauna 5018.

Police Const. François Collard says police have ruled out homicide, but the death could have been caused by a drug overdose or sudden illness.  

He said they are waiting for the results of an autopsy to determine the exact cause of death.

"Is it a cardiac arrest? Is it a health problem?" Collard asked. "The autopsy will help us decide."

Police say the body was discovered by an employee who was working alone at the time.
