Kenyan police officials say they have arrested two Kenyans who were deported from Turkey on suspicion of training with the Islamic State organization in neighboring Syria.

Philip Tuimur, the regional police boss for Kenya's coastal region, said the man and woman were under investigation Saturday for joining a banned group, which is a criminal offense.

A senior police source who insisted on anonymity because the source was not authorized to discuss the case said the two were arrested by Turkish authorities while entering from Syria in November after having gone for training with the IS group.

Kenya has been struggling to contain the recruitment of youth by extremist groups.
