[JURIST] A California state prison inmate who led a radical Islamist group and three others were indicted Wednesday [DOJ press release; AG Gonzales' remarks] on charges that they were plotting terror attacks on several sites in Los Angeles. The indictment [PDF text] charges Levar Haley Washington, Gregory Vernon Patterson, Hammad Riaz Samana and Kevin James with conspiring to wage war against the US government and to attack National Guard facilities and the Israeli Consulate. Prosecutors allege that James, a state prison inmate, founded the radical Islamist prison group Jamiyyat Ul-Islam Is-Saheeh [Los Angeles Times report] and recruited the three others to carry out plans by the organization. Washington and Patterson were both arrested in July after allegedly robbing a series of gas stations to finance their activities. Investigators found evidence of the plot in searching the apartment of Washington following his arrest. The case has raised questions [AP report] about the religious practices of prison inmates, who the FBI has said may be more susceptible to radical ideologies. AP has more.
