reuters Florida State News Reuters 20-NOV-97 (TAMPA) -- Federal marshals and local deputies have shut down three Tampa area ``pirate'' radio stations, silencing unlicensed sources of rock music and far-right ideology. Authorities carted off broadcast and studio equipment from all three stations and dismantled a rooftop antenna that stood over one broadcaster's home. One of the stations was operated by 53-year-old Arthur Kobres, who is named in a 14- count indictment alleging violations of national broadcasting laws. Authorities say Kobres used his equipment to broadcast anti-government messages. Also silenced was ``Tampa's Party Pirate,'' a 100-watt F-M station run by Doug Brewer. A third operator who was shut down... 22-year-old Kelly Benjamin... was also arrested for possession of marijuana.
