HOLLAND, MI (WHTC) - The Holland Public Safety Department has put up a five thousand-dollar reward for information leading to the arrest and conviction of those responsible for a series of anti-police graffiti. Over 50 “tagging” incidents believed to be related have been reported since December 2nd in a variety of locations and venues, with specific threats made to the “Holland Police Department.” Recent surveillance video images show two covered figures walking away from one of the scenes; that admittedly grainy image is posted on our website. No persons are in custody, and anyone with any information is asked to contact Holland Public Safety or Silent Observer.
