Updated at 5:30 p.m. with information about the vehicle.

A pickup driver repeatedly rammed the KDFW-TV (Channel 4) studios in downtown Dallas on Wednesday morning, ranting about treason and an officer-involved shooting from years ago before he was arrested, police said.

Michael Chadwick Fry, 34, was arrested on a felony count of criminal mischief, authorities said. His bail has yet to be determined.

Police were called to the 400 block of North Griffin Street just after 6 a.m. Anchors continued with their morning news report and calmly described what was happening as Fry got out of his truck after the crash and started to rant.

Fry scattered papers everywhere, Channel 4 reporter Brandon Todd said. The fliers included news coverage of an officer-involved shooting from 2012, when Fry was a passenger in a pickup that his companion rammed into a Denton County deputy's squad car at a traffic stop near Krum.

An officer shot and killed the driver, 21-year-old Roberto Hernandez.

"They tried to kill me. And they missed. And hit him," says a handwritten note scribbled in the margins of the flier. "They used brainwashing tactics."

Dallas police spokeswoman Debra Webb said Fry was "obviously in an agitated state." He was upset about an officer-involved shooting in another city, a subject addressed in the papers he scattered.

"Officers said he was rambling and just saying all kinds of nonsense," Webb said at a morning news conference.

Anisa Lee, a Starbucks employee who arrived after Chadwick was arrested, remembers him shouting as police investigated a bag he dropped near the building and blocked off the crime scene.

“He said, ‘They tried to kill me,’ and he just seemed really upset,” Lee said.

Fry has a lengthy criminal history in Denton County, where he was arrested on an assault charge earlier this year.

Police say a suspicious bag was found outside the Fox studio, but nothing harmful was discovered. The building was evacuated except for a skeleton crew that kept the station on air.

The truck he used was a rental from Enterprise Rent-A-Car, spokeswoman Laura Bryant said.

No injuries were reported.

FBI investigators were called to the scene, Webb said, but she didn't know the extent of the agency's involvement.

Webb said Fry's actions did not appear to be connected to any animosity toward the media.

"It's just concerning, no matter what the building is or who is inside," Webb said. "We're just fortunate in this case that no one was injured."

Dallas Area Rapid Transit suspended rail service in the area for about three hours before it resumed shortly after 9 a.m.

Around the same time, employees were allowed back into the building, police said.

Delivery driver Eugene Garcia was stuck on Griffin for several hours because of the police activity downtown. He wasn’t headed to the station that day, but says he delivers there often and was worried for the security guard’s safety when he first learned what happened.

“I’m just glad everyone there is safe,” Garcia said.
