Seven persons held at the cells are currently at large.
The police have, as a result, mounted a manhunt for them.
They are Nigerian Chibuzor Akwabu, 34, and Ghanaians Dickson Ofori, 24, Edem Rockson, 32, Prince osei, 27, Emmanuel Kotey, 21, Kofi Darko, 21, and Attah Kwadwo, 20.
The rest of the inmates have been transported to the Madina Divisional Police.
Meanwhile, the Accra Regional Police Command says investigations have begun into the matter and it is being done “with all the urgency it deserves”.
