NY DAILY NEWS:

    They would meet clandestinely inside school vans. He was a 13-year-old eighth-grader, she was the school's headmistress about to offer a disturbing lesson in lust.

    "She told me not to tell anyone," the victim, now a 24-year-old NYPD cop, testified in Manhattan Supreme Court, as he recalled the first time Lina Sinha planted a kiss on him. "She told me she could get in trouble."

    Sinha, 40, is accused of having a near-decade-long sexual relationship with her former student at an upper East Side Montessori school. She is also charged with later putting the moves on a 12-year-old boy.

    The schoolhouse stunner - whose family runs Montessori schools in Manhattan, Queens and Brooklyn - allegedly took special interest in the boys before crossing the line.

    "Just after his 15th birthday, she says she's going to give him a birthday present," prosecutor Rachel Hochauser told the jury in her opening statement.

    That, prosecutors contend, turned out to be a sex romp at the Brooklyn Montessori school.

    The steamy relationship allegedly extended through the boy's high school years and as he entered college and the Police Academy.

    "She wooed them both," Hochauser said. "The objects of Lina Sinha's affection, lust and greed were children."

    Defense lawyer Gerald Shargel blasted the district attorney's case as "pathetic" - and said the teacher never had sex with underage boys.

    But Shargel acknowledged Sinha did have a sexual relationship with the cop after he was of legal age and while he was in the Police Academy.
