More information from federal law enforcement sources on the Uzbekistan terrorist suspect who plowed into New York pedestrians on Tuesday shows that the 29-year-old immigrant had a printout of an ISIS flag in his car, and left behind handwritten notes in Arabic, pledging his loyalty to the Islamic State.

According to witnesses, Sayfullo Saipov shouted, “Allahu akbar,” (God is great) after the crash, which took place in the same area where the World Trade Center used to stand. The bright, beautiful Halloween afternoon was reminiscent of the type of gorgeous weather experienced on Sep. 11, 2001.

Saipov’s notes, written in Arabic and pledging loyalty to ISIS, turned up inside and near the vehicle, police told Fox News. In addition, the New York Post reported that investigators found “an image of the ISIS flag inside his vehicle.”

Saipov was shot by police before he was taken into custody and remains hospitalized. Eight people died in the attack and 11 were injured. Saipov, however, is expected to live.

Saipov came to the U.S. in 2010 through a program called the Diversity Immigrant Visa Program. According to The Associated Press, he has a Florida driver’s license but was said to be living in Paterson, N.J.

He was working as an Uber driver and had passed a background check, the company told Fox News. The company is offering to assist the FBI and ridiculously added that Saipov has now been banned from the app.

Four of the victims injured by the terrorist were teachers and students who were riding on a yellow school bus near Stuyvesant High School when they were hit by the suspect’s Home Depot rental truck. One student is reportedly in critical condition.
