Mackin ran east toward Monroe Street, but Sprecher followed him in his vehicle and caught up with him in the YMCA parking lot on the east side of Monroe Street near the Public Safety Building.
Sprecher told the Mackin he was a sheriff's employee, called 911 and stayed with the suspect until police arrived.
Mackin was booked into jail on a charge of second-degree vehicle prowling. He was released alter that morning on his own recognizance per a judge's order.
