(WHAS11) -- Louisville Metro Corrections unveiled an airport-style body scanner called the SecurPass Friday to the media, three weeks after it was installed at the jail.
It uses radiation to detect metals and other sensitive materials inmates may try to smuggle into the jail.
Officials say inmates try to smuggle drugs, cell phones, weapons, lighters, cigarettes and more, sometimes in body cavities that slips past corrections officers even in routine pat downs or strip searches.
The scanner cost about $250,000 and is one of just about 25 in jails nationwide, according to jail officials.
The arrival of the scanner comes as heroin has spiked in Metro Louisville and so has the number of inmate deaths in police custody.
