The diocese of Segorbe-Castellon said in a statement that the unnamed monk's superiors had taken action against him, Reuters reports.
"The Bishop expresses his dismay over the acts reported to the police which, if true, are unacceptable for Church and society," the statement said.
"He shares the pain of the victim, his parents and family and asks them for forgiveness," the statement said. "Not a single case of abuse by a priest is acceptable."
Several Spanish media said the Order had transferred the monk to a convent in northern Spain and banned him from being alone with children as a precautionary measure.
Media also reported that the order had passed on details of the suspected case to the public prosecution of the Supreme Court in Valencia.
