We begin with new video and new details from the brazen attack on a TV Baltimore station. A man seen here driving a truck through our ABC station before then engaging police in a tense, five-hour standoff. ABC's Pierre Thomas is learning more about the suspect. Reporter: Baltimore's WMAR TV station, under assault. This truck, ramming into its building five times before crashing through into the lobby. Only minutes earlier, the deranged driver had showed up at the station's front door screaming, I am god. I am god. Here he is, caught on tape, frustrated. Pacing, yanking on the door after security refused to let him in. He left but returned after stealing a nearby landscaping truck. You look and there's a truck coming through the glass in the front lobby. And people running. We got attacked today. We got attacked. Reporter: Worried they had an active shooter, S.W.A.T. Team soon moved in. Hold the air for a minute. I've got a truck entirely inside the building here. Reporter: Police searched the station and found the suspect watching TV coverage. This is where he was. And he sat right here. The individual was ranting and raving incoherent statements. Reporter: Our ABC family at WMAR Baltimore is so relieved no one got hurt. They know they're lucky. Look at the damage from that truck. For "Good morning America," Pierre Thomas, ABC news, Baltimore.
