We do not assess at this point that anyone else is involved in this attack except for Shamsud-Din Jabbar, the subject you’ve already been briefed on," Raia told reporters.
He added that the FBI does not see connections between the attack in New Orleans and the explosion in Las Vegas.
Raia reiterated that the law enforcement nave interviewed "many people" who know Jabbar and continue talking with others.
"Be clear, again: we do not believe at this point these people are involved in this incident in any way. We want to speak to them as witnesses, and want to know what they saw, and when," he added.
Police in Las Vegas said on Wednesday they were investigating a car fire near Trump Towers after a video of a burning Tesla Cybertruck went viral online. One person was confirmed dead in the blaze and seven others were injured, the local authorities said. An FBI spokesperson at a briefing did not call the incident a potential terrorist attack. However, ABC TV channel, citing sources, reported that law enforcers do not exclude such a version.
