One of the officers, Lance Corporal Kusi Abrokwah, was arrested earlier in a bush around Nkawkaw and handed over to police authorities nearby.
The Police in the Eastern Region have confirmed the arrest of the second suspect after a regional security council (REGSEC) meeting Thursday. His name was however withheld.
