A pair of men wearing Halloween masks robbed a Little Canada bank as it opened around 7 a.m. Thursday, the FBI reported.

The men forced two employees of the U.S. Bank at 2850 Rice Street to unlock the vault and place an undisclosed amount of money into a dark plastic garbage bag and a black gym bag with white trim, according to the FBI.

The suspects were described as black males about 6 feet tall.

One of the men, described as having a muscular build, wore a black hooded sweatshirt, black pants, black gloves and a red mask.

The other, who had a medium build, wore a black hooded sweatshirt, black pants, white gloves and a skeleton mask.

U.S. Bank is offering a reward of up to $25,000 for information on the bank robbers.

Anyone with information about the suspects or the robbery is asked to call the Minneapolis FBI at 763-569-8000, or the Ramsey County Sheriff's Office at 651-266-9350.
