A civilian employee accused of setting a co-worker on fire at a health center at Kansas’ Fort Leavenworth is facing an additional charge in a new federal indictment.

Grand jurors on Wednesday in Kansas City, Kansas, indicted 54-year-old Clifford Currie of Leavenworth with one count each of assault with intent to commit murder and of assault with a dangerous weapon.

The indictment replaces a complaint that charged Currie only with assault to commit murder.

Prosecutors allege Currie threw a flammable liquid on his female supervisor, lit her on fire and assaulted her with a straight edge razor and scissors. Authorities say another worker was injured when she tried to stop the assault before other hospital employees subdued Currie.

Messages left Wednesday with Currie’s public defenders weren’t immediately returned.
