FBI, Boulder Police Say Six Injured, Suspect in Custody After Downtown Boulder Attack

The Federal Bureau of Investigation and Boulder Police said at a joint news conference that six people were injured and a suspect is in custody after an attack in downtown Boulder, and investigators are treating the incident as an act of terrorism.

The news conference drew the FBI’s special agent in charge, Boulder Police Chief Steven Redford and Boulder County District Attorney Michael Dougherty, who said the investigation is ongoing and asked the public for digital and other evidence to assist the probe.

Officials said the six victims range in age from about 67 to 88. Four were taken to Boulder Community Health and two were airlifted to a Denver‑area burn unit; at least one victim was described as being in critical condition. The FBI said it had surged personnel to the scene and was processing a vehicle and other evidence. The suspect was taken into custody at the scene.

"We have surged resources and personnel to the scene," the Special Agent in Charge, Federal Bureau of Investigation, said. "Our special agents, our victim specialist, and evidence response teams are doing everything they can to assist our law enforcement partners." The agent added, "We will continue to support the victims and help uncover the events leading up to this terrible attack." The press conference included a spelling of the suspect’s name; when asked for the spelling, the special agent spelled it aloud as "Mohammed, m‑o‑h‑a‑m‑e‑d, Sabry, s‑a‑b‑r‑y, Soliman, s‑o‑l‑i‑m‑a‑n."(1)

Chief Steven Redford, Boulder Police Department, described the scene response and safety measures. "Our officers, as they're trained, immediately interacted with the suspect, took him into custody, and then began rendering aid to those victims," Redford said. He said downtown blocks around the courthouse remained closed while investigators cleared the area, and he announced the courthouse would be closed the following day. Redford said multiple K‑9 and bomb‑squad teams were conducting checks and that the department was deploying resources to other events in town to maintain public safety.

District Attorney Michael Dougherty said his office and the U.S. Attorney’s Office were in contact and would decide in the coming days what charges to file and in which venue. "We're in the very early stages here," Dougherty said. "Decisions will be made about what charges to file and where. There's a couple different options. But what I would stress now, most importantly, is we are fully united 100% in making sure the charges we bring hold the attacker fully accountable."

Officials asked the public for assistance. The FBI directed people with tips to call 1‑800‑CALL‑FBI and asked anyone with digital evidence — video or social posts — to submit it at fbi.gov/boulderattack. The Special Agent in Charge said interviews and forensic processing of the scene and the suspect’s vehicle were ongoing, and that checks for potential links to other actors were underway but had not identified any co‑conspirators. When asked about early reports of multiple suspects, the special agent said those initial reports had not been confirmed and investigators were "fairly confident we have the lone suspect in custody," while noting work continued.

The news conference concluded with officials urging calm and community support for victims. "Any attempt to divide us through fear or harm has no place in Boulder, in Colorado, or anywhere in our nation," the Special Agent in Charge said. "We stand in full solidarity with those targeted, and we will continue to ensure that justice is pursued swiftly."
