WASHINGTON — The FBI on Tuesday arrested a Florida man who federal authorities say detonated an explosive device in a Capitol tunnel tunnel during a fierce battle between Trump supporters and law enforcement officials on Jan. 6.

Daniel Ball of Homosassa is charged with 12 counts, including assaulting, resisting, or impeding officers with a deadly or dangerous weapon; using an explosive to commit any felony; and obstruction of law enforcement during civil disorder.

He is the only defendant charged on January 6 with setting off an explosive device during the attack on the Capitol.

Authorities say the 38-year-old Ball «worked with other rioters to violently push fully uniformed police officers who were trying to keep people out of the Capitol building» and then «threw an explosive device into the driveway.»

Several officers suffered from the effects of the blast, the FBI said. One described «hearing impairment lasting for months»; another described the pain from his ringing ears as a 10/10 on the pain scale and said he temporarily lost his hearing and his hearing was affected for at least two days. Another officer reported ringing in his ears for nearly three hours, while another said the ringing lasted well into the next day, according to the FBI.

“For many other officers who were interviewed, it was the most memorable event of that day,” an FBI affidavit said. “Some officers who were defending the tunnel at the time of the explosion reported feeling the pressure of the blast. Some thought it was a fragmentation grenade and anticipated significant pain or injury. Some thought they were going to die. Some officers suffered psychological trauma from the blast.»

An FBI explosives and dangerous device examiner in the Explosives Unit of the FBI laboratory in Huntsville, Alabama, «was unable to conclusively identify the precise dimensions, size of the charge, or whether the released explosive device was improvised or commercially manufactured.» «, according to the FBI, but concluded that it was «capable of inflicting damage to surrounding property, as well as seriously injuring people in the vicinity of the resulting explosion.»

In the affidavit, the FBI said that a few months after the attack on the Capitol, Ball was arrested in Florida and charged with assault on five civilians and two law enforcement officers. The FBI said he was found guilty in connection with the incident and sentenced to five years of probation.

The FBI said Ball’s probation officer confirmed his identification for Tuesday’s arrest, which appears to have been made with the help of facial recognition technology. “That’s Daniel Ball,” the probation officer said when shown a photo, according to the FBI. The probation officer added that Ball was still in possession of the jacket he was wearing on Jan. 6, 2021, authorities said.

Ball’s attorney did not immediately respond to a request for comment Tuesday night.

The use of explosive devices by the pro-Trump mob on January 6 was extremely rare.

David Lee Judd set off what appeared to be a firecracker, but it did not go off. He was sentenced to more than two and a half years in federal prison for his role in the attack on the Capitol.

The FBI is still searching for the person or people who left pipe bombs outside the Republican and Democratic National Committee headquarters on January 6. Shortly before the two-year anniversary of the riots, the FBI increased the reward to $500,000 for information leading to the attack. arrest of anyone involved in planting the homemade bombs, which did not explode.
