Police were dispatched to a disturbance call at the Walmart after 10 p.m.

The Sheriff's Office told WJAX a man inside the store was making employees feel uncomfortable. The man was asked to leave by employees, but refused.

When the man eventually left the building, an officer approached him. When that happened, the man crouched down as if he was hiding something, keeping one hand out of the officer's view, police said.

Deputies said the man then sprayed the officer in the face with an unknown substance. The officer then fired three shots, killing the man, WJAX reported.

The Sheriff's Office identified the officer as S. Doreseliun and said he has been with the department for three years. This is the deputy's first officer-involved shooting. The man who died has not yet been identified.

Doreseliun has been placed on administrative leave, per Sheriff's Office policy, as the investigation continues.

Police were still at the Walmart investigating after 6 a.m.
