Queens Primary-School Teacher Charged With Sexually Abusing Student February 23, 2012, 2:10 pm A teacher in Queens was arrested Thursday on charges of sexually abusing a student younger than 11, becoming the fifth city teacher charged in the last few weeks with sexual crimes against children. The teacher, Brett Picou, 30, of Public School 52 in Springfield Gardens, was charged with repeated sexual conduct against a child and endangering the welfare of a child, the police said. No details were immediately available on the child's age or sex, on what Mr. Picou is accused of doing, his disciplinary history or on whether the contact was said to have occurred on school grounds. The school, on 146th Terrace, goes up to fifth grade. The police were notified of the accusations against Mr. Picou on Feb. 16, a police spokesman said. The recent string of charges against teachers, several of them with histories of sexual contact with children buried in their personnel records, prompted the schools chancellor, Dennis M. Walcott, to order a review last week of all substantiated cases of misconduct since 2000; he pledged to fire any teachers who had engaged in sexually inappropriate behavior. The series began with news on Feb. 7 that a teacher's aide in Crown Heights, Brooklyn, had been charged with making videos of his sexual acts with children. Then a teacher's aide on the Upper West Side was arrested on sexual abuse charges after a male student told investigators the man had him strip in the school's bathroom and, at another point, offering money to fondle the boy. On Feb. 16, a computer teacher in Queens with a history of inappropriately touching children was arrested on charges of inappropriately touching an 8-year-old and a 9-year-old boy. And on Wednesday, a substitute high school teacher in the Bronx was arrested on charges that he twisted a 16-year-old male student's nipples.
