The electrician, Bernard Perez, was brought into the police station by cops who’d pulled him over because they thought he was suspected on a warrant. When it turned out that Perez didn’t meet the fugitive’s profile, the officers arrested him on the gravity knife charge.
Prosecutors dropped the case against Perez after, in the District Attorney’s office, one of the arresting cops failed several attempts to demonstrate that the knife Perez was carrying at the time of the arrest could flick open.
