GAINESVILLE, Ga. — Authorities say police fatally shot a gunman who had taken hostages at a dermatology office in Georgia.

The Georgia Bureau of Investigation has been asked to investigate the shooting Monday morning in Gainesville, which is common practice for officer-involved shootings in the state.

Kevin Holbrook said the gunman was holding workers and others hostage inside the office, and officers shot the man when he brandished a gun as they approached him.

Holbrook said the gunman died after being taken to a hospital. His name has not been released.

Gainesville police said in a statement that no one else was injured.
