Agents with the Federal Bureau of Investigation raided the studios of a Hawaiian public access television station this week.

On Thursday, several FBI agents were spotted entering the studios of Na Leo TV, a not-for-profit public access television station and production company that operates three channels on local cable systems.

A special agent who was present at the raid declined to answer most questions posed by reporters, including why federal officers were searching the television station.

“It’s just a search,” Jason White, a special agent with the FBI’s Honolulu office, told the Hawaii Tribune-Herald.

“The case is ongoing,” he said. “We’re not going to give out any details other than confirming it is us [carrying out the search].”

City and county law enforcement said they were not notified of the raid prior to its execution on Thursday.

Micah Alameda, the assistant general manager of the station, told a local newspaper the station was “fully cooperating” with federal investigators.
