A Rockville man has been charged with committing sexual offenses against two adult women he met through a dating app, county police said Thursday.

Colin Sime Black, 33, works as a guidance counselor at Albert Einstein High School in Kensington, but the charges do not relate to any Montgomery County Public Schools students or any minors, according to the school system.

Both women involved in the case told investigators they met Black through the dating app Tinder.

One woman said she agreed to meet Black on March 24 at his Rockville apartment, where the two had consensual sex, according to a police press release. Black then committed sexual acts without the woman’s consent, the release stated. The woman reported the encounter to police the same day.

Authorities in September learned that Black possibly committed offenses against a second woman and spoke with her on Oct. 3, the release stated. The woman said she met Black through the dating app in 2016 and drove to his home on Dec. 31. After the two had consensual sex, Black committed sex acts that the woman hadn’t agreed to, police reported.

The two women do not know one another, and the second woman was not aware of the ongoing investigation against Black when she spoke to police in October, according to the release.

Black, who lived on Clemson Court in Rockville, was arrested Thursday and charged with two counts of second-degree sex offense and second-degree assault.

In a letter to parents on Thursday, Einstein’s principal wrote that MCPS had just learned of the allegations against Black, who had been employed with school system since 2009. In addition to working as a guidance counselor, Black spent time as a coach at Einstein and a substitute teacher for MCPS, the letter stated.

“These charges are deeply troubling. This type of behavior does not reflect the principles of MCPS or our community, and it will not be tolerated,” Principal James Fernandez wrote.

MCPS will be placing Black on administrative leave, district spokeswoman Gboyinde Onijala wrote in an email.
