Arrested again: Former Reagan High School teacher accused of sexual assault of a student

MILWAUKEE (WITI) -- Milwaukee police on Thursday, April 11 confirmed the arrest of Kenneth Chu — a former teacher at Ronald Reagan High School. On March 27, Chu pleaded guilty to multiple charges after prosecutors said he was involved in inappropriate communication with students at the school.

Police said Chu was re-arrested on April 9 — for sexual assault of a student by a teacher. Formal charges had not been filed as of Thursday.

FOX6 News reached out to Milwaukee Public Schools officials and Chu's attorney for comment on the latest arrest. We haven't yet heard back.

Chu, 27, in March pleaded guilty to four counts — causing a child 13-18 to view sex activity and three counts of exposing a child to harmful material. He will be sentenced on June 3.

According to the criminal complaint, school officials received a complaint from an alum that Chu “was reaching out to recent graduates and flirting with them.” He had apparently “created several fake social media accounts to follow and chat with female graduates.”

Because of the complaint from the alum, Chu was escorted from the building — and a 16-year-old girl was later asked to speak with police and the principal at the school.

The criminal complaint indicates Chu starting communicating with the 16-year-old via Snapchat in the summer 2018. The complaint said Chu would ask the girl “if she wanted to sneak off and fool around” — and he began to send pictures to the girl of himself naked. The complaint indicates Chu demanded the girl send him photos of a similar nature — and “kept threatening her, saying he had the power to suspend her.” The complaint indicates there were other moments when Chu “asked (the girl) under his breath if she wanted to sneak off with him and 'mess around.'” The complaint also said Chu sent the girl “video and images of his naked body approximately 40 times. This would occur on school nights and weekends.” One text message said he was “crushing pretty hard.” Another read, “I've fallen for you.”
