WARREN (WKZO) -- Two Warren men face multiple charges after posting threats and threatening pictures towards police on the social media site Facebook.

Eighteen-year-old Richard William Walker and 20-year-old Michael Davis face a misdemeanor charge of malicious use of telecommunications device along with felony charges of possessing a short-barrel shotgun,  and resisting and obstructing a police officer.  An anonymous tip led police to Walker's home where they found shotguns, rifles, a handgun, crossbow, mini-cannon, and cases of ammunition and about 10,000-dollars in fireworks.

Both men remain in the Macomb County jail, unable to post 50,000-dollar bail.
