Police and fire officials have cleared Roper St. Francis Hospital following a bomb threat Sunday afternoon.

According to Charleston County Dispatch, police responded to the hospital just after 1 p.m. after receiving a call about a threat at the hospital. Charleston police and firefighters responded.

Andy Lyons, director of corporate communications for Roper St. Francis, said a woman came into the emergency room earlier in the day, became upset and made threatening statements. When hospital security staff escorted the woman back to her car in the hospital's parking garage they thought they spotted possible bomb making materials including a bag of fertilizer and a can of gasoline, Lyons said.

A bomb squad and HAZMAT crew determined that no dangerous materials were in the car. Lyons said the woman has been taken to another facility for evaluation. No charges will be filed in the incident.
