The suspect was taken to hospital and remains in police custody.
Mr Erlij was celebrating a 30-year reunion in New York with his former schoolmates from the General San Martín Polytechnic Institute in Rosario.
Minutes before the New York attack, he had called his wife, Pabla Pereyra, in Rosario to tell her he was riding a bike and was feeling very happy.
A friend of the couple, Flavia Gauna, recalled that Mr Erlij often said that “if it weren’t for the United States, the world would no longer exist because of these crazy [terrorists]. And look what happened.”
Misaskim, an American Orthodox Jewish not-for-profit organisation which provides services for the care of the dead, is reported to have worked with the New York City Medical Examiner’s Office to ensure that Mr Erlij’s body was handled according to Jewish custom.
However, the family decided on a non-religious funeral service.
Ezequiel Cazorla, general manager of the steel production company which Mr Erlij owned, Ivanar in Rosario, said that the businessman’s widow and children – aged 19, 17 and 14 – had preferred a private burial.
“There is too much pain. They cannot speak,” he said.
The Israeli Prime Minister, Benjamin Netanyahu, telephoned the governor of New York, Andrew Cuomo, shortly after the attack to express his condemnation, condolences and support.
Argentina’s President, Mauricio Macri, travelled to New York to express his solidarity with the five murdered Argentinians.
“We were all very shocked when we heard we had lost five residents of Rosario who were showing off one of Argentina’s finest qualities, friendship,” Mr Macri declared.
He added that terrorism and violence must be fought with the greatest vigour: “We want to live in a world governed by peace.”
Mr Erlij, the most financially successful of his old schoolmates, was the driving force behind the trip to New York, helping to foot the bill for at least two of those who could not afford it.
He was active in politics in his home city and the surrounding province of Santa Fé and promoted a number of investment projects in the region.
He was also a passionate fan of his local soccer team, Rosario Central, and they paid tribute to him on Saturday before their match with Atlético Tucumán.
A neighbour, Averio Ososky, described Mr Erlij as “an entrepreneur, a working type. Sheer gold.”
His friends at his volleyball club affectionately nicknamed him “The Mummy” because he had difficulty bending his knees on the court.
Mr Cazorla said Mr Erlij was “a great creative force. We will continue our work with the same strength and we will always remember him with enormous love.”
