The upper legislature asked its Committee on Sports and Youth Development to investigate whether the recent appointment by the Chief of Army Staff, Tukur Buratai, was in order.
Buratai had recently appointed Ibrahim to replace Brig-Gen Sule Kazaure as the NYSC boss.
The committee investigating the matter was asked to submit its report on Wednesday next week.
The committee members were saddled with the responsibility of finding out if any law was violated in the appointment of the new NYSC boss.
The decision to investigate the matter was based on a point of order raised by Senator Dino Melaye.
The senator had claimed that the appointment violated the Act that established the body.
He said, “The NYSC Act, Section 5, says there shall be a service to be headed by a person called the Director-General, to be appointed by the President.
“Surprisingly, the Chief of Army Staff removed the Director-General through a signal and, through another signal, appointed another one.
“The law doesn’t confer the power of appointing NYSC DG on anybody, but the President. The last DG and all other past DGs were appointed by sitting Presidents.
“If we allow this, the announcement of the Senate President can come from the Federal Road Safety and replacement may come from the same institution.”
