MINNEAPOLIS — Federal charges have been filed against a man accused of ambushing an armored truck guard filling an ATM inside a St. Paul gas station and fleeing with $70,000.

Christopher “Pooby” Ward was charged Wednesday with robbery in connection with the predawn stickup at a SuperAmerica on Jan. 14, 2011.

Police say Ward also made off with the guard’s gun.

Photographs from surveillance video showed the gunman, dressed in black, confronting the Dunbar Armored Inc. guard while the Wells Fargo ATM was open. The suspect grappled with the employee and pointed his gun at least twice.

The guard was unhurt. Police say a second Dunbar employee remained in the truck.

Federal authorities say Ward has been apprehended. Online court records do not list a defense attorney.
