Three Baltimore police officers are going on trial on charges of kidnapping two teenagers and abandoning them.

The trial for the three officers begins Thursday in Baltimore Circuit Court.

The officers, Milton Smith, Tyrone Francis and Gregory Hellen, are charged with kidnapping the teens in May 2009 in separate incidents.

Authorities say the officers assigned to the violent crimes impact division picked up the 15-year-olds in a police van. They released one teen in east Baltimore and the other in Patapsco Valley State Park in Howard County.

State’s Attorney Greg Bernstein will prosecute the case — his first since taking office in January. Bernstein is a former federal prosecutor and defense attorney.
