The Federal Bureau of Investigations along with the Naval Criminal Investigative Service conducted a raid Thursday in a San Jose neighborhood.
Investigators were seen going in and out of a home located at 6901 Salamanca Ave., right at the intersection of San Jose Boulevard.
An FBI spokesperson said there was no "imminent threat" to anyone in the area.
The investigation is an active partnership between the FBI and NCIS, and agents were seen taking things out of the house in evidence boxes.
Investigators said more information would be released Friday.
First Coast News learned the Clay County Sheriff's K9 Ty was used in the investigation for his "special skills" to “make sure we didn’t miss anything”, according to an FBI spokesperson.
First Coast News previously did a story on Ty's ability to sniff out technology that may contain child porn.
At this time, no further information is known.
