A janitor at a Brooklyn elementary school was charged today with raping and sodomizing an 8-year-old girl in a school bathroom.

Francis Evelyn, 58, of Brooklyn, was charged eight days after the unidentified student told her mother of the attacks, which allegedly occurred between Feb. 1 and March 9, police said.

The numerous sexual assaults took place during school hours in a basement bathroom adjacent to the cafeteria at Public School 91 in Wingate, cops said.

Bail for Francis Evelyn, 58, was set at $150,000 during his arraignment on rape, sex
abuse and other charges. His attorney denied any wrongdoing.

Evelyn does not have any prior arrests, police said.

The girl was examined by doctors before the man's 3:30 p.m. arrest yesterday, a police source said.

But investigators were not able to take DNA evidence from the student because the last alleged encounter occurred 10 days before the arrest, the source said.

Evelyn faces rape, criminal sex act, sexual abuse and endangering the welfare of a child charges, officials said.
