He escaped Immigration and Customs Enforcement agents, who were going to escort him onto the plane, when they took off his handcuffs so that he could pass through security.
The Daily News reports, citing law enforcement sources, that the man is considered to be a "violent deportee". Video surveillance shows the man leaving JFK in a cab.
The Port Authority released a statement after the incident: "An individual being transported by federal immigration officials at JFK Airport last night eluded custody during transfer to a connecting flight". He is 6 feet 3 inches and weighs about 190 pounds. Federal authorities would know if he is still at large.
Port Authority officers were notified about the escape 45 minutes after it occurred.
Mbacke had entered the country lawfully in 2005 but had been convicted of weapons and firearms offenses, Walls said.
In September 2015, a immigration judge approved an order for Mbacke's deportation. "Members of the public should not to attempt to apprehend him and instead immediately contact authorities".
