CHARLESTON, SC (WCSC) - Authorities say a suspicious letter found at the Dock Street Theatre on Monday contained non-dairy coffee creamer.
Charleston Fire Battalion Chief Mike Julazadeh said firefighters, EMS, police, and Haz-Mat crews responded to 135 Church Street around 12:40 p.m. after receiving reports of a suspicious letter.
Capt. Ryan Kunitzer with CFD says the suspicious package was determined to have a power-like substance contained inside. Authorities say after careful review of the substance, that originated from an envelope mailed to the facility, the substance was determined to be non-dairy coffee creamer.
Emergency crews then cleared the scene at 4:30 p.m. Six employees at the theater were being held inside in the building as police and Haz-Mat crews investigated the letter.
Charleston police spokesman Charles Francis said six employees were being "isolated" until the investigation on the envelope was completed.
This is the second time this month a suspicious letter has turned up in downtown Charleston. On July 8, Haz-Mat crews responded to Historic Charleston Foundation on East Bay Street near the Battery after white powder was found in a plastic bag inside an envelope.
The powder was determined to be baking soda a short time later.
