The bill is sponsored by Sen. Michael Hough, a Frederick County Republican. It reflects continuing efforts to address a contraband scandal at the Baltimore City Detention Center that resulted in the indictments of 44 people, including 27 correctional officers, in 2013.

The corrections department says there are 7,132 authorized correctional officer positions. There are currently about 328 vacant entry positions.
