Gunmen attacked the Adamawa State Police Headquarters in the wee hours of Wednesday, sending residents of Yola into panic.
The Police headquarters is located at the heart of Jimeta community in Yola North local government area.
Sounds of gunshot rend the air for at least 30 minutes, according to a resident who preferred anonymity.
Police Public Relations Officer, SP Suleiman Yahaya Nguroje, confirmed the attack to Daily Trust, but said things were under control.
Nguroje said the attack was repelled, but the identities of those behind it was unknown.
One source said the attackers were military personnel on a revenge mission, following the alleged killing of a military officer by the police.
Although Daily Trust could not independently verify if military personnel were involved, the police said investigations were ongoing to ascertain the cause of the attack and those behind it.
The development comes some days after the stand-off between officials of the Economic and Financial Crimes Commission (EFCC) and personnel of the Nigerian Air Force.
Air Force personnel had invaded EFCC head office in Kaduna state to effect the release of their colleagues arrested over alleged fraud.
The military personnel and security operatives guarding the commission almost exchanged gunfire, according to sources.
The anti-graft agency later issued a statement to say it would not be intimidated in the course of duty.
Inter-agency clash sometimes occur between operatives, and have sometimes led to bloody bath.
Daily Trust will bring you update of the Adamawa incident as events unfold.
