The youth were intercepted in Plateau State.
The Nigerian military on Thursday said it had intercepted about 51 youth moving from Maiduguri, Borno State, to Abuja.
This was disclosed via an unsigned statement on its website.
The military said the convoy was intercepted around 3 a.m. along Babale, Plateau State on Wednesday.
The youth, travelling in three 18-seater transit buses, were led by a woman, it said.
It added that officers of the Special Task Force were currently trying to unravel the motive of the youth movement.
The statement also disclosed that during an interrogation, the youth claimed they were being conveyed to Abuja on the order of a Borno State Government official, to meet their relatives for assistance in an economic empowerment programme. It also said the youth had made contradictory statements regarding sponsorship of their mission to Abuja.
The military, however, added that efforts to reach the official, to verify the claims, were not responded, adding that the issue was being investigated to ascertain the genuine mission of the young people.
It said the investigation had become necessary in the light of the security situation and the suspicious claims by the youth.
