A nursery worker has admitted 31 sex offences involving children.
Jamie Chapman pleaded guilty to 22 counts of causing or inciting sexual activity with children, including the rape of a teenage boy, and nine counts of making and distributing indecent photos, West Midlands Police said.
The 28-year-old, from Solihull, appeared at Birmingham Crown Court.
He was remanded in custody to reappear at the same court on 22 May for sentencing.
At the time of Mr Chapman's arrest last November, police said there was no evidence to suggest inappropriate contact between him and children at the nursery where he worked.
