A woman has been accused of attempted murder at a private girls school in downtown Charleston today.

Officials at Ashley Hall school told police a woman pointed a gun at a school official on the sidewalk in front of the school at 172 Rutledge Ave., according to Charleston police spokesman Charles Francis.

The school official went inside and told somebody to call police about 3:22 p.m. Police arrived within minutes and detained the woman on the sidewalk before she entered the campus, Francis said.

Alice Boland, 28, of Beaufort was arrested and charged with attempted murder. She’s being held in the Charleston County jail.

Several police cruisers parked outside the school, and the school was on lockdown until shortly after 4 p.m.

Students were sending each other messages that a woman with a gun had walked onto the campus.

A student leaving the school about 4:30 p.m. said she had been forced to stay late because of the lockdown, but nobody told her why.

Police left the school about 4:45 p.m.
