The F.B.I. on Sunday arrested George Pierre Tanios, 39, in West Virginia and Julian Elie Khater, 32, in New Jersey on charges of assaulting officers, including Officer Sicknick, with bear spray.
The arrests came weeks after investigators pinpointed one of the men in a video of the riot, in which he was seen attacking several officers with the spray, according to two law enforcement officials. The Justice Department has said in earlier court filings that rioters were recorded on video talking about attacking officers, including Officer Sicknick.
It is not clear whether Officer Sicknick died because of his exposure to the spray. On Jan. 7, the day that he died, the Capitol Police said in a statement he “was injured while physically engaging with protesters” at the riot a day earlier and then “returned to his division office and collapsed.” He later died at a hospital.
