NEW YORK -- Officials said Wednesday night they found a man they were seeking for questioning in connection to the New York City terror attack.
Prior to a Wednesday evening press conference, the FBI released the person's name as Mukhammadzoir Kadirov of Uzbekistan, born November 5, 1984.
Then during the briefing, FBI officials said they found Kadirov but didn't publicly elaborate on him or whether he has provided information to them.
Although, CBS News has learned from a high ranking law enforcement official that Kadirov is "a friend" of the attack suspect and that Kadirov "may not have a role at all" in the incident. Kadirov is being questioned by authorities now; investigators became suspicious of him because Kadirov "went off the radar" when they went to talk to him following Tuesday's attack.
The FBI tweeted that anyone with information about him should contact them at 1-800-CALL-FBI.
Meanwhile, an investigation is underway after two Americans, five Argentine nationals and a Belgian were killed when an attackerin New York City on Tuesday, authorities said. One of the dead was a young mother, and others were classmates who traveled to New York to celebrate 30 years since their high school graduation.
The suspect in Tuesday's deadly terror attack in New York City -- Sayfullo Habibullaevic Saipov -- was because his name was associated with the subjects of other FBI counterterrorism investigations in 2015, an intelligence source said, CBS News' Pat Milton reports.
An intelligence source confirms to CBS News that Saipov had some contact with those individuals who were considered radicalized extremists and at least one of whom was from his native Uzbekistan.
Federal prosecutorsWednesday against Saipov.
Saipov, 29, is charged with two terrorism counts: a charge of providing material support to a terrorist organization and a charge of violence and destruction of a motor vehicle with willful disregard for human life.
The complaint says he drove the truck down the bike lane intentionally.
Officials say Saipov planned the New York City attack for months and did a test run on October 22.
Also found in the complaint filed by federal prosecutors:
Saipov waived his Miranda rights before the interview in a hospital room at Bellevue Hospital
Saipov requested to display the ISIS flag in his hospital room and stated that he felt good about what he had done
On one of Saipov's two cell phones he had about 90 videos and thousands of images that are "ISIS related propaganda"
