A heroic security guard took down gunman who drove into Citibank’s office campus outside Tampa, Florida and shot a woman.

New surveillance footage shows Jacob Pearson, 35, of Orlando, driving a sedan through a fence and into an outside seating area where he shot and killed LeAnne Selman, 41 on November 4.

Pearson is then seen stalking through an office building where he was shot by the unnamed security guard. He later died in hospital.

Pearson was reportedly unhappy about a $2,500 debt owed to Citibank.
