WINNEBAGO — Winnebago Mayor Scott Robertson and his son Jacob Robertson were arrested Thursday following a drug raid on three Winnebago properties.

The Robertsons were transported to the Faribault County Jail for alleged cultivation of marijuana offenses, according to a South Central Drug Investigative Unit (SCDIU) news release.

About 240 plants believed to be marijuana and many other items of evidence were seized at 15/17 Main Street, 522 1st Ave. S.W. and 18195 340th Avenue.

An investigation by the SCDIU, Faribault County Sheriff’s Office, Faribault County Attorney’s Office and other law enforcement agencies began in early 2023, according to the news release.

Scott Robertson was in his second year of a two-year mayoral term, according to the Winnebago City Clerk Office.
