(CBS News) A Maryland special education teacher is accused of trying to film female students while they changed clothes, reports CBS Baltimore.

Police say Christopher Clark, of Milford Mill Academy high school in Baltimore County, tried to use his cellphone to videotape the school’s cheerleading team changing in his classroom.

Baltimore County police spokeswoman Jennifer Peach tells local news outlets that 46-year-old Clark faces one voyeurism-related charge. He was charged in a criminal summons Friday.

Charging documents say Clark admitted that he propped his cellphone on his desk, pressed record and then left his classroom to allow the cheerleaders to change into their uniforms on Jan. 23.
