The Nigeria Broadcasting Commission (NBC) has suspended the license of Daar Communication Plc until further notice.
Daar Communication Plc owns African Independent Television (AIT) and Ray Power radio station.
NBC director-general Modibbo Kawu announced the shut down on Thursday evening.
Although Kawu said the action was taken for failure of the broadcasting station to abide by the NBC’s broadcasting code, critics see the move as President Muhammadu Buhari’s way of crushing dissent.
Daar Communication Plc is owned by Peoples Democratic Party (PDP) figure Raymond Dokpesi.
The NBC had accused the AIT of breaking broadcasting codes in the use of social media posts during its programmes.
