A Bronx teacher accused of raping his 10-year-old student sent her a repulsive e-mail after the attack, saying he was “too rough” — but rationalizing that “it’s normal,” prosecutors say.

Anthony Criscuolo, 40, sent the e-mail to the fifth-grader from PS 386 in Fordham Heights on Tuesday — just one day after cops say he raped her in his car.

“I was too rough. Sorry. It’s normal,” he wrote in the sickening note.

“You may feel pain for a few days,” he added.

As if that weren’t twisted enough, he asked, “How did it feel for you?”

The teacher had told the child’s parents he was escorting her to receive an award at a school ceremony on Monday — but instead he drove her to a school parking lot on Ward Avenue and raped her, cops say.

Yesterday, a Bronx Criminal Court judge ordered Criscuolo held in lieu of $750,000 bond or $500,000 cash bail.

During the attack, he placed his arms on the girl’s arms, legs and chest, according to a criminal complaint.

The twisted trysts took place repeatedly beginning in April — at least one of them in a building on East 181st Street, according to the complaint.

During one of the alleged attacks, Criscuolo kissed the girl on the mouth, unbuckled her belt, then told her, “I like you,” according to the complaint.

He continued, “I’m doing this because I like you. I don’t want you to feel uncomfortable . . . If you feel uncomfortable, ask me to stop,” the affidavit states.

When the girl’s mother found sexually explicit e-mails, she alerted police.

The Bronx Special Victims Squad opened an investigation that culminated in the teacher’s arrest on Wednesday.

Cops charged Criscuolo with rape, predatory sexual assault against a child, and endangering the welfare of a child.

Students later told the The Post they had noticed the special-ed teacher and the girl playing husband and wife on occasion.

He had even bought her a real diamond ring, students claimed.

The pair was also acting strange at a Valentine’s Day party, students said, noting they were “dancing real close.”

Cops say Criscuolo raped the girl in his silver Dodge Charger, which has tinted windows.

A Department of Education spokeswoman said on Wednesday the agency plans to fire the teacher.

Criscuolo had no disciplinary record before the arrest.

The complaint claims the acts he allegedly committed were “injurious to the physical, mental or moral welfare of a child.”

Criscuolo started as substitute in The Bronx in 2002.
