PORT ST. LUCIE (CBSMiami/AP) — A Florida man reportedly set a fire in a woman’s home after a dispute.

The Port St. Lucie Police Department says 30-year-old Richard Caldwell was arrested Saturday and charged with arson and burglary.

Police said Caldwell was involved in a dispute with the victim at a bar before she left with friends to go home. The woman found Caldwell inside her house, asked him to leave, and he said “you’re going to regret this,” while holding a bottle with lighter fluid.

The woman left and returned to find her home engulfed in flames.

Caldwell returned, and a K-9 trained dog detected fire accelerants on his shoes and in his vehicle.
