WICHITA, Kan. (AP) — Prosecutors say an anti-Muslim militia group in Kansas first came to the government’s attention when one member contacted FBI agents and became a confidential source.

The new details came in a government court filing in the case of three men accused of conspiring to detonate truck bombs at an apartment complex where 120 Somali immigrants live in the western Kansas meatpacking town of Garden City.

Prosecutors say the men pose a “substantial danger” to the community and should stay jailed until trial.

Two are due in court Friday and the third on Monday.

Patrick Stein, Gavin Wright and Curtis Allen are charged with conspiring to use a weapon of mass destruction. They were arrested in what the government calls a foiled plot to attack the apartment complex on Nov. 9.
