State Law Enforcement Division agents were called to George Street overnight after meth-making materials were found, possibly left by squatters, on the roof of a College of Charleston dorm, officials said.

According to College of Charleston spokesman Mike Robertson, George Street Apartments’ housing officials received a call around 1 a.m. from a CVS employee complaining of water dripping into the store from the above upperclassmen dorm.

A search for the leak led to the discovery of two one-liter bottles on the roof. Robertson said the bottles contained a suspicious liquid substance and Public Safety officers with the school were notified. Charleston police, firefighters, a Hazmat team and SLED agents were also called to the dorm.

Authorities determined that the materials were consistent with those used to make meth, Robertson said.

Sleeping bags were also found on the roof, SLED spokesman Thom Berry said. All of the materials were secured by the Charleston Bomb Squad and firefighters, Berry said.

According to Robertson, a nearby parking garage could grant anyone access to the area where the materials were found.

There was no need to evacuate the building while the investigation was conducted. Robertson said the dorm was fairly empty as most students had already left for Thanksgiving break.

SLED is handling the ongoing investigation, Robertson said.
