Police have arrested and charged a 27-year-old Toronto man who allegedly failed to tell his sexual partners he had HIV.

Police said Ala Al Safi was diagnosed with HIV in February 2011 and then proceeded to have sex with at least two men without telling them about his status.

Al Safi met one of the men, a 24-year-old, via an online classified ad in July 2011. The other, a 21-year-old, he met on an online dating site last December.

It’s alleged Al Safi failed to tell either man about his HIV status, and both contracted the virus.

Police have charged Al Safi with two counts of aggravated sexual assault.

He appeared in court on Monday morning.
