RICHMOND (AP) — An off-duty firefighter tackled a woman who investigators say was trying to set a person on fire in the San Francisco Bay Area.

KNTV reports Monday that 24-year-old Nai Feuy Saelor of Richmond was seen Sunday throwing lighter fluid on a 50-year-old woman at a house on Mount Tamalpais in Marin County.

The off-duty firefighter tackled the woman before she could set the woman on fire.

No serious injuries were reported.

The Richmond woman was booked on suspicion of arson, assault with a caustic chemical and vandalism, the television station reports.

The vandalism count stems from the woman allegedly scrawling in red paint the words “rapist” and “murderer” on the home.

Investigators say she could be linked to several other fires in the area.
