Police have arrested someone in the firebombing of Texas state Sen. Wendy Davis' office in Fort Worth, an official with the city's fire department told TPM on Wednesday morning.
Fire Capt. Tom Crow said the person was arrested overnight and police and fire officials would be holding an 11 a.m. ET news conference to reveal the attacker's name, photograph and more details of the investigation.
Crow also said federal investigators with the US Bureau of Alcohol, Tobacco, Firearms and Explosives had joined the probe.
Davis, a Democrat, was not in the office when a pair of Molotov cocktails hit its door on Tuesday afternoon, but two of her staffers were. One of them quickly put out the fire. No one was hurt.
It is still unclear whether the attack was politically motivated, Crow said.
"I don't have any information regarding motivations right now," he said. "That’s not to say it is or it isn’t. I’m just not aware of it."
