FORT WORTH (AP) – A homeless man accused of throwing a bag filled with six Molotov cocktails at the office of state Sen. Wendy Davis last month has been charged with arson.

The Tarrant County Criminal District Attorney’s Office says 40-year-old Cedric Steele was formally charged Tuesday with the second-degree felony punishable by two to 20 years in prison.

Steele was arrested March 20, hours after the incident in which no one was injured. Investigators say he tried unsuccessfully to speak to Davis in the days before the alleged attack and talked of aliens after his arrest.

Davis wasn’t in her Senate district office when staffers heard fire alarms and smelled a strange odor. They opened the door to find burning bottles and waist-high flames, which they put out with a fire extinguisher.
