WICHITA, Kan. (AP) — Prosecutors say the three Kansas men accused of conspiring to attack Somali immigrants in Garden City pose a “substantial danger” to the community and should not be released pending trial.

A filing Thursday makes public new details about the plot and the arsenal they had amassed. The government also cited the men’s backgrounds, arguing they pose a flight risk.

Detention hearings for Patrick Stein and Gavin Wright are set for Friday, and one for Curtis Allen is set for Monday.

The three are charged with conspiring to use a weapon of mass destruction.

Prosecutors say the men were part of a small militia group called the Crusaders. They allege the three planned to detonate truck bombs around a small Garden City apartment complex where about 120 Somali immigrants live.
