Internal complaints allege lying, pranking, excessive force by Chattanooga police officer under investigation for punching man at traffic stop

This frame grab from video shows Chattanooga police officer Benjamin Piazza punching 37-year-old Fredrico Wolfe several times during a traffic stop on March 3, 2018.

A Chattanooga police officer under investigation for punching a man several times during a recent traffic stop has a history of internal complaints alleging rude behavior, lying to supervisors about turning in evidence on time, excessive force and playing a prank on colleagues that made them believe they were getting shot at, a review of his personnel file shows.

The Times Free Press received a copy of Benjamin Piazza's file Tuesday after first publishing body camera footage Friday that showed him punching Fredrico Wolfe, 37, during a March 2018 traffic stop on Lee Highway.

Though Wolfe tossed a bag of drugs out of his window after Piazza pulled him over, the video showed Wolfe otherwise following the officer's orders. Both police Chief David Roddy and Chattanooga Mayor Andy Berke issued statements in support of an internal investigation, which no one had requested before the video emerged.
