A Queens public school teacher has been arrested on rape charges, accused of having sex with a 14-year-old former student, law enforcement sources said. 

Daniel Reilly, 36, who taught at I.S. 237 in Flushing, was charged with two counts of first-degree rape, 10 counts of second-degree rape and seven counts of endangering the welfare of a child, police said. 

Law enforcement sources said Reilly had a sexual relationship with a 14-year-old girl who was once his student. A family member found out about the relationship and reported it to police.

Police say the sexual relationship began in November. The latest alleged sexual encounter was in April.

Margie Feinberg, a spokeswoman for the Department of Education, said Reilly had been a teacher at the Flushing school for five years. He was reassigned pending the outcome of the investigation, she said. 

Reilly was released on $50,000 bail after his arraignment Tuesday. His attorney, Eric Franz, said he returned home to his wife and 11-month-old child after the court appearance.

Franz did not comment on the allegations. He said his client is a former Marine who was honorably discharged before he started teaching.

Reilly is due back in court next month. Police say he has no prior arrests. 

Queens District Attorney Richard Brown called the allegations "troubling."
