It was a scary morning for employees at the Wells Fargo Bank in Marquez.
The Leon County Sheriff's Office says the bank was robbed about 9:30 this morning.
According to the department, the robber used a pistol and possibly a hand grenade, before making off with what investigators call a large amount of cash.
No bank employees were hurt, but they were locked in a bathroom, and threatened with violence if they escaped.
Texas Rangers, the FBI, and Leon County sheriff's investigators are still looking for the robber, and any possible accomplices.
Suspect descriptions are vague, because they say the man was wearing a disguise.
