A former Maryland teacher allegedly engaged in sex acts with an underage middle school student, according to police, who said there could be more victims.

Melissa Marie Curtis, who's now 31, was a teacher in Montgomery Village Middle School in Montgomery County, Maryland, when the alleged abuse happened in 2015, according to police.

It allegedly continued for "several months" when Curtis was 22, police said.

The victim, who's now an adult, came forward in early October, which sparked an investigation into the former teacher.
