Arson charges are expected after someone threw an incendiary device into a home in Northwest Jacksonville on Sunday night.
The home in the 6000 block of Zinnia Avenue was occupied by two people, ages 83 and 55.
One of them heard a window break and found a bed on fire, according to a police report.
Neither person was hurt.
A neighbor gave police a description of a person spotted in the rear of the house, and that person was taken into custody a few blocks away, according to the report.
The occupants of the fire-damaged home told police they've had issues with the suspect.
