At least eight people were killed and 11 seriously injured when a rental truck ploughed into pedestrians and cyclists on a bike path near the World Trade Centre memorial in a what officials called a terrorist attack.
Those who died in New York City on Tuesday include five Argentinian friends celebrating the 30th anniversary of their graduation and a Belgian, but what do we know about the suspect?
He is a 29-year-old from Uzbekistan called Sayfullo Saipov, according to law enforcement sources speaking on the condition of anonymity.
He entered the US legally in 2010 and holds a Florida driver’s licence but could have been living in New Jersey, they added.
Saipov had been working as an Uber driver after passing a background check, according to a spokeswoman for the app who said it is cooperating with the FBI.
Police shot him in the abdomen after he leaped out of the vehicle while touting two imitation guns but he was expected to survive after undergoing surgery, authorities said.
At least one friend acted with shock that Saipov could be the man behind the atrocity.
Kobiljon Matkarov told NBC News that Saipov, who he met five years ago when they lived in Florida, ‘is no terrorist’. He is a ‘very happy’ married father who worked as a truck driver and ‘liked the US’, the friend added.
One woman, Dilnoza Abdusamatova, 24, said Saipov moved to the US six years ago and stayed with her family in Cincinnati for his first two weeks as their fathers were friends, The Washington Post reported.
But he moved to Florida to form a trucking company and lost touch when he got married, she added.
The suspect rented the Home Depot truck in New Jersey at around 2pm before driving into the bike path around an hour later.
New York governor Andrew Cuomo described it as a ‘lone wolf’ attack, suggesting the suspect acted alone and was not part of a wider network.Let's
