The Fulton County Jail locked down for hours Saturday afternoon after reports of a weapon inside the jail.
The scare came about a month after an inmate was shot inside by another inmate.
Atlanta police and sheriff's deputies surrounded the main gate of the jail while it was on lock-down for several hours.
Sources told Channel 2s Michael Buczyner a guard working on the seventh floor thought he spotted an inmate with a gun. That's the same floor in the jail where an inmate shot another just last month..
Families and even employees were forced to wait outside during the lock-down, allowing no one in and no one out, and very little information.
Sources told Buczyner that a SWAT team and guards swept through the maximum security floor and although a gun wasn't found, Buczyner learned that a shank wrapped in a uniform was recovered during the sweep.
A recent Channel 2 investigation showed contraband found during jail cell searches including scissors, knives, drugs and even cell phones.
According to jail officials, inmates housed on the seventh floor are not allowed physical contact with the public.
So the question remains, how did the shank end up on the seventh floor?
Jail officials said they are still investigating the incident.
