An employee of the Glenwood Country Day School has been arrested by Howard County Police and charged with sexual abuse of a minor, police officials said Friday.

Dameon Patterson, 31, of Elkridge, is facing counts of sex abuse of a minor, rape and other sex offenses, according to online court records. An attorney listed in online court records for Patterson declined to comment.

Patterson has worked in the Glenwood Country Day School’s before- and after-school programs and summer camps for about two years, police said.

The Glenwood Country Day School is a private school in Howard County. Its website says it offers pre- and after-school care for students in the Howard County Public School System. A message left at the school went unreturned as of Friday night.

On Saturday, the principals from three public elementary schools and one public middle school in Howard County sent an email to families about the investigation and arrest because their students may have attended the after-school program at Glenwood, a county schools spokesperson said.

The email said Patterson was in charge of the before and after school programs and summer camps at Glenwood over the past three years.

“If your child has participated in any of these programs, we encourage you to talk with them to determine if they have had any inappropriate contact with this employee, Dameon Patterson,” the email said.

Last week, the victim told a child about being abused, and that friend told an adult, police said. Detectives started an investigation last week, and Patterson was arrested Thursday.

The 11-year-old victim told investigators that the abuse happened over the course of two years, according to court documents. She told investigators it happened at the Glenwood Country Day School and that there were “numerous” incidents of abuse.

The Glenwood Country Day School was ordered to stop providing care immediately by Maryland State Department of Education Office of Child Care on Jan. 5, Raven Hill, a spokeswoman for the department, said.

The school had failed to immediately notify the Office of Child Care about an employee who was under investigation for a criminal charge or allegation of child abuse, Hill said in an email. The office is still investigating, she said.

Patterson was released on $10,000 bond Friday, according to court records.

Detectives are asking anyone with information, including any other children who may have been victimized by Patterson, to contact police at 410-313-STOP.
