PATERSON- The man taken into custody by the New York Police Department after Tuesday's terror attack that killed at least eight is 29-year-old Sayfullo Saipov of Tampa, Florida, according to an ABC News report. He is an Uzbek national and came to the U.S. in 2010.

Saipov also has ties to New Jersey.

On Tuesday night, police had surrounded an area that included an apartment building, a mosque, and several other residences and storefronts. Paterson police said it was a New York FBI terrorist task force investigation, but that Paterson officers were in charge of crowd control and traffic. As of 11 p.m. officers were searching a garage in the neighborhood where residents said Saipov lives.

Around 2 a.m. Wednesday investigators in FBI jackets arrived in a convoy of SUVs and began inspecting the area around the apartment building.

Paterson Councilman Alex Mendez said he was "very concerned" that the suspected attacker lived in Paterson and called the attack an "isolated incident."

"We have 52 nationalities. They're hardworking people that come to Paterson to start a better life," he said.

A man who said he was Saipov's neighbor and did not want to be identified said he often saw the suspect around the neighborhood with his wife and two children. He also said he saw Saipov drive a white Toyota Sienna with Florida plates.

Another neighbor, 64-year-old Slavo Petrov, said Saipov lived in his building in an upstairs apartment for less than a year with his family. Saipov was unfriendly, he said, and "never says good morning and never says good afternoon".

Petrov said he attended the local mosque and had seen Saipov there. But Omar, a 17-year-old boy who attends mosque five times a day, said he had never seen Saipov at prayer.

Saipov has no known criminal record, but has been stopped for traffic violations in Pennsylvania.

Police stopped Saipov in Mount Holly Springs Borough, Pennsylvania, just south of Carlisle, in March 2015 and he gave police a Paterson, New Jersey address, according to police records. He also was stopped in 2012 in Palmyra, Pennsylvania, just east of Hershey.

Uber confirmed to NJAM that Saipov passed a background check and drove for the company in New Jersey but has since been banned from the app. Uber said it is researching Saipov's history as a driver but a spokesman said the company has "not identified any related concerning safety reports." Uber is cooperating with the FBI to assist in its investigation.

In New York city, two law enforcement officials told the New York Times that investigators discovered handwritten notes in Arabic near the truck that indicated allegiance to ISIS. Officials said Saipov yelled "God is great" in Arabic.

Videos from the attack posted online show Saipov dodging cars in lower Manhattan, horns beeping in the background. ABC News interviewed a witness who said he saw Saipov run toward a group of children. Police have said the objects Saipov was holding were imitation firearms.
