A disgusted dad says he returned home early to find Tajreed Rich, 41, naked with his teen daughter in her bedroom in Minneapolis.

Tajreed Rich, a 41-year-old hall monitor, member of the football coaching staff, and student counselor at Robbinsdale Cooper High School, allegedly had sex with a 17-year-old student.

A Minneapolis high school hall monitor was busted in bed with a 17-year-old student — by her father.

The disgusted dad returned home early Friday to find a naked Tajreed Rich, 41, standing over his disrobed daughter in her bedroom.

Confronted with most dads’ worst nightmare, he resisted handing out his own justice and called cops.

Rich was arrested and charged with sexual assault later that day.
