Police said Barry Marchinkoski, of Middletown, was attempting to steal razor blades and lighters when he was stopped by security guards at the store. Marchinkoski threatened the guard with a knife and fled on foot through the parking lot.
Police found a pocket knife in his pants pocket along with heroin, suboxone and needles.
His bond was set at $50,000 and is scheduled to appear in court on Thursday.
