Federal agents working in tandem with the Portage County Sheriff's Department are serving numerous search warrants July 18 at properties affiliated with Sugar Bush Knolls resident Davood Haghighi, owner of Globe Auto Sales on S.R. 59 in Ravenna.

Investigators with the Internal Revenue Service, Drug Enforcement Administration and the sheriff's department began serving the warrants around 8:30 a.m. Thursday morning.

Portage County Sheriff David Doak said warrants being carried out are the result of a two-year investigation, but would not otherwise comment.

He said Haghighi is not currently under arrest.
