Update 12:30 p.m. - Casper Police responded to a hold-up alarm at the downtown Wells Fargo Bank drive-through shortly after 11:00 a.m. Friday. Officer Lyle Berg says police were called after the alarm was tripped, but it appears bank employees did not follow the established protocol for such a situtation. Although no robbery occurred, without proper confirmation by bank workers, five officers secured the perimeter of the bank. The bank was cleared by noon. Police continue their investigation.
