The embattled leader of the Islamic Movement in Nigeria (IMN), Sheikh Ibrahim El-Zakzaky and his wife, Zeenat are on their way to India.
They flew out to India on an Emirate flight on Monday evening from the Nnamdi Azikiwe International Airport in Abuja.
They were arrested in December 2015 and have remained in DSS detention since, amidst reports of deteriorating health.
A High Court in Kaduna granted the detained couple bail on Monday to enable them embark on the medical trip.
