A 22-year-old man has been accused of faking emergency calls and jamming or otherwise disrupting the Des Moines Police Department's radio frequency.
Kevin Grimes, of Webster Township, has been charged with 28 counts of obstructing emergency communications and eight counts of impersonating public officials.
Police say he made calls this month that forced the dispatch of officers, vehicles and equipment to the scenes of nonexistent incidents.
Police also say Grimes would leave his radio set on the police frequency without talking on it, tying up the channel.
Online records say Grimes remained in Polk County Jail on Thursday. Online court records don't list the name of his attorney.
