(ABCNEWS.GO) — An Illinois special-needs teaching assistant accused of molesting a teenage student in school while knowingly infected with HIV remained jailed Tuesday as police investigated another claim of similar misconduct by the man involving a different student.

Prosecutors in St. Clair County east of St. Louis charged Mario L. Hunt, 35, on Monday with felony counts of criminal sexual assault, aggravated criminal sexual abuse and “transmitting” HIV through intimate contact during the first half of 2011, when the student was 17. The transmission charge means a defendant merely exposed a victim to the virus that causes AIDS, not necessarily causing actual infection.

Cahokia police Lt. Dennis Plew said Tuesday he was unaware whether the teenager, now 19 and still a student at Cahokia High School, has been tested for HIV.
