They were rounded up and arrested at the NYSC Orientation Camp in Kubwa, Abuja, on Thursday evening while they were posing and taking pictures outside the camp during the passing-out ceremony.
The ICPC, in a statement, said its operatives stormed the camp based on intelligence reports and arrested the suspects comprising eight females and nine males.
It said preliminary investigation revealed that 15 of the suspects claimed to have enrolled in degree courses run by consultancy services in the University of Calabar (6), University of Jos (6), Ebonyi State University (1), Federal University of Technology, Owerri (1) and Crown Polytechnic, Ado-Ekiti (1).
Another suspect, a young man, impersonated his sister, a genuine corps member who was receiving medical treatment abroad, in order to collect her discharge certificate.
One of the fake corps members, the commission noted, never attended any university, but said she wanted to get an NYSC discharge certificate.
Employers, parents and guardians have thus been warned to confirm from the NYSC if they were suspicious of any person submitting call-up letters, posting letters, discharged and exemption certificates.
