DETROIT — An ex-convict has been charged with using the internet to threaten police officers who attended the funeral of a Detroit officer.

The FBI says Deshawn Lanton threatened to “drop a bomb” on a St. Clair Shores church last Friday during the funeral of Sgt. Ken Steil, who was shot while chasing a suspect. Investigators say the threat was made on Facebook.

The FBI says Lanton is on probation and has convictions for fleeing police, resisting police and other crimes.

He appeared in federal court Wednesday and was returned to jail. An attorney will be assigned. A hearing will be held Thursday to determine if he’ll be granted bond.

Police Chief James Craig says he will “relentlessly” pursue anyone who threatens a Detroit officer.
