The 31-year-old junior military officer was lynched after he was mistaken for a thief.
Speaking at a news conference at the National Police Headquarters in Accra Friday, Mr Oduro said seven of them are on remand including the assemblyman of the area who is alleged to have incited the mob.
According to him, they have been charged with murder.
Speaking at the same event, the Inspector General of Police vowed to bring all those who took part in the heinous crime to book.
The Chief of Defense Staff, who was also at the programme, expressed satisfaction at the work of the police in arresting the suspects.
He said: “Yesterday [Thursday], I held a durbar and the issues raised had to do with the speedy investigation and prosecution of those who carried out this dastardly act, and I gave assurance that a high powered team had been sent to the incident area, and I am happy to hear from the Director General and the CID and also from the IGP that indeed they are making progress.
“We look forward to a speedy investigation so that those who are found culpable face the full rigors of the law because justice delayed is justice denied.”
