A 24-year-old Annapolis man charged with sexually abusing a child he was hired to babysit said he is "ashamed" and has apologized to the victim's family.

Anne Arundel County Police said Andrew Dickinson Grabau, of Annapolis, was arrested on a warrant charging him with sex abuse of a minor, third- and fourth-degree sex offenses, and second-degree assault. The investigation stemmed from allegations that he abused a child, who he had been hired to babysit, on numerous occasions between April 2013 and October 2013.

Grabau was released on $25,000 bond. Reached for comment, a man answering the phone who identified himself as Andrew Grabau said he was "very ashamed for what I did" and had "repented" and "reconciled with the family, indirectly."

Police asked anyone with additional information to call Detective Joshua Williams at 410-222-3484.
