An angry Brooklyn dad turned the tables on a school aide trying to date his teenage daughter by posing as the girl in texts to catch the creep, authorities say.

The father went undercover after finding inappropriate messages between his child and former High School for Enterprise, Business and Technology staffer Dyke St. Rose on the teen’s phone, according to the city schools’ Office of Special Commissioner of Investigation.

St. Rose, 24, had showered the girl with texts — the pair exchanged 1,140 messages over three months this past spring — saying he wanted to give her rides home and “kiss her lips,’’ the SCI report said.

The teen’s father discovered the illicit exchanges after the girl left her iPhone in his car and he looked through it, the document states.

“In a fit of rage, Student A’s father [then] snapped the phone in half,” according to the report.

The device was so badly damaged that it was impossible to retrieve any evidence from it, the document said.

So the dad began posing as his kid, sending texts to the lunch and hallway monitor from another number, the papers state.

But the father’s command of teenage lingo apparently fell short because St. Rose soon smelled something fishy in their exchanges.

The school aide was “unnerved because he was not sure whether Student A was the person sending the messages,” the report states.

“St. Rose asked Student A several questions to prove her identity, and when Student A did not know the answers, he called the phone number,” and the dad’s masquerade was up, according to the report.

The girl’s parents reported St. Rose’s behavior to school officials, and the dad also once confronted the aide at school, with the two men having “words” over his pursuit of his daughter, the papers state.

St. Rose eventually admitted to school officials that he tried to date the student, acknowledging that his behavior was a “bad and stupid mistake,’’ the papers state.

But the clueless former aide added that no one ever told him that he couldn’t have “a relationship with a student,’’ according to the document.

He was suspended and resigned in July.

St. Rose told The Post that he has since joined the military. He declined to comment on the case, saying only that it has been “cleared up.”

DOE spokesman Will Mantell, stressing that St. Rose is no longer with the department, called his behavior “unacceptable.’’
