Remarkable video has been released showing the moment when Harrison Okene - who had been trapped for 60 hours 30m underwater in a capsized boat - was rescued by divers.

The ship's cook had taken refuge in an air pocket. Divers from the DCN global diving company had been searching the remains of the tugboat, which sank to the bottom of the ocean off the Nigerian coast in May, in order to recover the bodies of the sailors.
