Defence chief Christopher Musa has ordered a thorough investigation into the alleged deaths of two Okuama community leaders while in army custody.
Okuama had been in the news over the unfortunate killing of 17 army officers and soldiers in the community.
“Let only those who committed the crime be brought to book. Let the innocent be spared,” said the Ijaw community leader.
Mr Seigha described the killing as barbaric, saying there must be justice for the slain soldiers.
“This should be done with respect to relevant laws, swiftly and equitably,” the forum said.
Oil money, mixed with militancy and violent local politics in the area, has created and nurtured private armies with money, weapons and political clout comparable to rogue states.
The wanted persons include seven men and one woman.
“I want to make it clear, once more, that those who committed this heinous crime will not go unpunished.”
The remains of 17 military personnel killed in Okuama in Delta on March 14 have arrived at the National Military Cemetery, Abuja, for burial.
The military has been urged to protect innocent residents as they search for the masterminds of the attack that killed 16 soldiers in Okuama.
