HOUSTON -

The FBI is looking for four men who robbed a Houston credit union; and, one of the robbers had a unique disguise.

The four men went into the Texas Dow Employees Credit Union on W. 19th Street at 3:11 p.m. Tuesday.

Officials said at least one of them had a gun. The armed man pointed the handgun to employees and verbally demanded money.
