A Detroit man accused of making threatening posts on social media about a mass shooting was arrested on Wednesday in Youngstown.

U.S. Marshals arrested 28-year-old Cameron White at a house in the 900 block of State Street.

Wednesday morning, a warrant was issued for White’s arrest about posts that White was “planning a massive shooting real soon,” according to U.S. Marshals.

Police in the Detroit area contacted U.S. Marshals because it was believed that White was hiding in Youngstown before carrying out the shooting in Michigan.

White is being held in Mahoning County until he can be extradited to Detroit to face charges of terroristic threats and computer crimes.

U.S. Marshal Pete Elliott said, “Immediate attention to this dangerous suspect by the Detroit police department and the U.S. Marshal’s task force in Detroit led to a swift and safe arrest by the task force in Youngstown. We will continue to partner with our state and local law enforcement agencies to keep suspects like White off the streets and our communities safe.”
