Belleville police say a 60-year-old man is facing sexual assault charges after an incident involving a 17-year-old boy they describe as “vulnerable.”

Police would not expand on the vulnerable description but did not deny the victim may be living with a mental health issue or a physical disability.

The alleged incident took place late August at an apartment building in Belleville’s east end.

Police say the suspect befriended and lured the vulnerable teen and invited him to his apartment to commit sexual assaults.

Thomas Ball of Belleville is scheduled to appear in court October 23.
