El Segundo police have arrested a 63-year-old woman accused of setting fire to seven buildings in the city, including a yarn store and two churches, between Aug. 17 and Aug. 24.

Barbara Nania of El Segundo, arrested Aug. 28, faces seven counts of arson and an additional terrorism charge for allegedly setting fire to St Michael’s Episcopal Church on Richmond Street during a service on Aug. 24, Los Angeles County District Attorney’s office spokeswoman Jane Robison said.

Nania, who faces up to 13 years and four months in prison if convicted, pleaded not guilty during an arraignment hearing on Tuesday.

El Segundo Police Lt. Jaime Bermudez said investigators identified Nania from surveillance camera footage.

No one was injured in the fires.
