A Kansas man will stay behind bars until trial for his role in an alleged conspiracy by a militia group to detonate truck bombs at an apartment complex where 120 Somali immigrants live.

Curtis Allen waived his detention hearing Monday and entered a not guilty plea, the only plea a federal magistrate judge can accept at this stage of the court proceedings.

Allen and co-defendants Patrick Stein and Gavin Wright are charged with conspiring to use a weapon of mass destruction in the meatpacking town of Garden City.

Prosecutors allege they are part of a militia group that calls itself “The Crusaders.” The government contends they planned to attack the apartment complex, which contains a mosque in one of the units, the day after the November election.
