A Bushwick principal has been reassigned after authorities say they caught her smuggling heroin and prescription drugs into an upstate prison.

40-year-old Sadie Silver was arrested on Friday after she and boyfriend Michael Acosta, 34, allegedly attempted to bring heroin and painkillers into Coxsackie Correctional Facility, a men's maximum security prison located about two hours north of the city. Silver's son, Alex Mercado, is reportedly an inmate at the prison, and cops say Silver's 10-year-old daughter was with the couple during their visit; they have been charged with child endangerment, along with drug charges.

Both Silver and Acosta were released on bond, and a spokesperson for the Department of Education tells us Silver has been "reassigned away from the classroom." Silver, who has worked with the DOE since September 1996, was lauded for her school's success in students’ reading and math test scores in 2012, and was profiled by the Daily News. "We’ve come a long way; we’ve worked very hard,” Silver, who dropped out of high school as a teen mother, told the tabloid. “It’s a work in progress and we won’t stop until we get all students reading at or above level.”

This isn't the first time Silver's gotten in trouble. In 2012, she had to pay a $1,500 fine after the city's Conflict of Interest Board found she used her position and influence to help her brother get a job.
