GRAND RAPIDS (WZZM) - A federal air marshal from Manchester, Michigan could face 93 days in jail if he is convicted of a June attack.
A judge Thursday formally charged Matthew Davids, 34, with misdemeanor assault. Davids has been an air marshall for five years.
Davids was with other federal officers and friends outside a Grand Rapids bar when a man in their group allegedly punched a man, knocking him unconscious. Davids is accused of attacking Cody Zink, who tried to help the unconscious man.
"The guy that was walking after me kicked me-- kicked me in the testicles... I was quite surprised by that. I don't know anybody that really uses that in a tactic in a fight, that's kind of dirty," said Zink.
Jon Holdsworth, who is accused of throwing the first punch, is also accused of assault and battery. Holdsworth is a former Ferris State football player who now has a body building business in Ohio.
The Transportation Security Agency would not comment on the investigation or any marshal's current duty status.
WZZM 13 On Your Side first reported the attack earlier this month.
