In the audio, Mr El-Zakzaky accused the Nigerian government of frustrating his medical treatment in India.
Speaking in Hausa, he said the situation at the hospital in India is “pathetic and worrisome”.
Mr El-Zakzaky said the management of Medanta Hospital, New Delhi, had been threatened not to admit him for treatment.
“The hospital officials received us well they told us that they parked two ambulance vehicles, deceiving the crowd while taking us out through another way, saying that it was for our own safety.
“On getting to the hospital, we were placed under a tighter security situation worse than what we have been witnessed in Nigeria. We are currently more confined than when we were in Nigeria, worse than a prison setting.
“Contrary to what was agreed before our arrival, that our own personal doctors would supervise this treatment. Now they’ve changed the arrangement. So, we objected receiving treatment from strange doctors without the supervision of our own trusted physicians,’’ he noted
The audio, the IMN leader said he wants to return to Nigeria to source for a reliable and trusted hospital among those countries that offered help.
“There are some other countries that volunteered to help which include Malaysia, Turkey,’’ Mr El-Zakzaky said.
