The Nigeria Police Force says its investigation shows that Boko Haram, Ansaru and other terror groups are getting support from some Nigerians.
This was contained in a press statement by the Force Public Relations Officer, DCP Frank Mba.
However, the statement did not give details of the individuals supporting the terrorists.
Mba, who described as unfortunate the support given to terror groups by the Nigerians, said three additional terrorists have been arrested after the invasion of Ansaru camp in Kaduna.
Earlier, Mba said 250 terrorists and bandits were neutralised in the raid last Wednesday.
He noted that police operatives were on close trail of other fleeing members of the terror groups and their collaborators.
