Three search warrants served Tuesday morning by federal and local law enforcement officials involved "Internet crime," and federal authorities took one person into custody later Tuesday, Sheriff Bobby Grubbs said Wednesday.

Grubbs did not release other details on the search warrants. Grubbs also did not reveal the identity of the person arrested by federal authorities or the charge. Grubbs had said Tuesday morning no one was arrested, and, Grubbs said, no one had been arrested when he made that statement. 

Another person, Debra Noll, 40, who was at a site where one of the search warrants was served, was charged with possession of a controlled substance (methamphetamine), Grubbs said. He said the charge was "incidental to the search warrant."

About 30 federal and local law enforcement officials executed three search warrants — one in the county and two in Brownwood —beginning around 6 a.m., Grubbs said earlier.

Grubbs has said he can disclose little about the search warrants or the investigation that led to the warrants, but said they did not involve firearms.

The Department of Homeland Security was the lead agency, and sheriff's deputies assisted in serving the warrants, Grubbs said. Officials with the U.S. Marshal's Service were also present.
