The captain and crew in charge of the Chinese fishing vessel were granted bail after their initial arrest and statements were taken.
Mr Essien got missing on July 5, 2019, and family members of Essien have been calling for justice, but police investigations remained inconclusive on the matter after two years.
Responding to a question on the matter at a media briefing in Accra on Wednesday, Mr Nana Kwabena Boakye-Boampong, Acting Director in charge of Maritime Services at the Ghana Maritime Authority, said the Authority did not have a full report on the investigation conducted by the Marine Police into the matter.
He said even though Mr Essien's missing had been validated by the Authority, his whereabouts could not be ascertained as the Police investigation was inconclusive.
Information Minister Kojo Oppong Nkrumah, expressed the need for the Marine Police Division to provide a status report on the case since the issue was of public interest.
He said it was imperative for the Chinese officials in charge of the fishing vessel to be held accountable and urged the media to follow up on the matter with the Marine Police for explanations.
