The FBI has a suspect for last years anthrax attacks, but is "dragging its heels" because he is a former government scientist familiar with secret state-sponsored research, a leading American expert on biological warfare said yesterday. The man also sent a hoax letter to the US Senate from Britain and may once have worked in the laboratory to which his letters were sent for testing, said Barbara Rosenberg, director of the Federation of American Scientists chemical and biological weapons working group. Quoted in the Trenton Times of New Jersey - based in the town to which most of the genuine anthrax mailings have been traced - Professor Rosenberg said that investigators had interrogated the suspect twice since October.
