Texas state Sen. Wendy Davis

Fort Worth police arrested a homeless man Tuesday night who they believe is responsible for setting off makeshift bombs at the office of state Sen. Wendy Davis, D-Fort Worth.

A bag of six bottles filled with lighter fluid were ignited outside Davis’ office around 4 p.m. Tuesday, starting a small fire. No one was injured, and Davis, a strong supporter of the LGBT community, was not in her office at the time.

Cedric Steele, 40, was arrested in a convenience store parking lot Tuesday night. He allegedly visited Davis’ office on West Seventh Street near downtown Fort Worth on Friday and again on Monday to speak to her about a tazing incident in Michigan.

During the arrest, he spoke of aliens, Police Chief Jeffrey Halstead said at a press conference outside the office Tuesday night. Police found igniter fluid and bottles in the abandoned house where police believe Steele was staying.

Steele has was convicted three times for criminal trespassing and once for assault family violence between 2006 ad 2010, according to Dallas County records. He was convicted of the misdemeanor of failure to identify in 2007 in Tarrant County.

Steel is being held on a $50,000 bond. He faces the second-degree felony charge of arson, punishable by up to 20 years in the Texas Department of Criminal Justice, according to the Texas Penal Code.

Last year, Davis authored a fully LGBT-inclusive anti-bullying bill. Before running for Senate, she served on the Fort Worth City Council and appointed the openly gay Joel Burns to the Plan Commission. When Davis stepped down to run for Senate, Burns was elected to her old seat.

Calls made to Davis’ office were not immediately returned.
