The man seen here allegedly robbed the U.S. Bank in Jackson on New Year's EveJACKSON — The Federal Bureau of Investigation and local police are both seeking a suspect who robbed U.S. Bank in Jackson Monday and took with him a substantial, though unreleased amount of cash, according to various sources.

Police obtained surveillance images from a local gas station, which allegedly ties the suspect to a slate-metallic gray 2007-2009 Toyota Tundra pickup truck with aftermarket rims and a shell displaying a large decal. The truck appears to have out-of-state plates, though it is difficult to identify which state given the grainy nature of the image.

The suspect is described as a 6-foot-2 white male in his 40s, muscularly built to slightly obese, weighing upward of 300 pounds. He has short, possibly shaved hair with pimples on the back of his neck and head. At the time of the robbery, surveillance images from the bank showed him with a graying mustache and goatee combo, an "English-style" cap and Oakley-style sunglasses, according to a Teton County Emergency Management release on the robbery. He also wore a silver-colored watch on his left hand and a white button-down shirt under a dark black overcoat. He spoke with what was described as "a strong South African accent or similar," though it is unclear whether the accent was affected or genuine.

Another surveillance image of the truck tied to a U.S. Bank robbery suspect in Jackson Hole, Wyo.

Police were notified as the robbery was in progress and arrived on the scene within two minutes, only to find out the suspect had already fled the area on foot in an unknown direction. The suspect did not use a weapon during the robbery, but police chatter around the time of the robbery reportedly mentioned military explosives. The area was swept for explosives and declared free of explosives within an hour of the initial call.

Other details on the robbery remain under wraps.

Sightings of the man or his vehicle should be reported to Teton County Dispatch at 307-733-2331 or the Jackson Police Department at 307-733-1430. Police don't want anyone to approach the man or the vehicle, as he may be dangerous.
