A substitute physical education teacher at a Central City school is under investigation for allegedly raping a 7-year-old student, New Orleans police and Orleans Parish School Board officials said Tuesday.

The substitute teacher, who was not identified, had not been arrested as of Tuesday evening.

Stan Smith, interim superintendent of the School Board, said the incident allegedly happened sometime last week on the campus of Mahalia Jackson Elementary School in the 2400 block of Jackson Avenue. The boy’s parents reported it to school officials Monday, he said.

According to an overnight crime log, police were notified of the incident about 8:40 a.m. Monday.

A Police Department spokesman declined to say when the incident is believed to have occurred, citing the ongoing investigation.

The crime log listed the incident as an aggravated rape.

Smith could not immediately say how long the substitute teacher had worked at the school but did say the teacher will not return to campus anytime soon.

“That person is not going to be substituting until this issue is resolved,” Smith said.

A person must pass a background check to be able to work for the School Board as a substitute or full-time employee, Smith said. The person under investigation underwent a background check and passed it, he said.

“There was nothing in the background check that noted anything on this individual,” Smith said.

There have been no other reports of similar incidents at the school, which has about 200 students in pre-kindergarten through third grade, or with the substitute.

“This is the only one we’re aware of,” Smith said.
