Abuja: Gunmen attacked a police station in Nigeria's northern state of Sokoto, killing six people, including four police officers.

The bandits lodged an attack at the police station with two vehicles on Tuesday apparently to rescue a suspected armed robber who was detained within in Tambuwal local government area.

The assailants first killed a police constable who stopped them from entering the police station. They subsequently entered the building and shot three other policemen, besides two other persons to death.
They then broke into the armoury, and made away with rifles, ammunitions before moving on to free a suspected armed robber detained at the station.

"One suspect has been arrested after the incident and the police are currently conducting investigation to unravel those behind the heinous act," Sokoto State Police Commissioner, Baba Adisa Bolanta said.
He ruled out the possibility of involvement of the radical Islamic sect Boko Haram which is active in Nigeria's north. The African country of 150 million people has a weak police often accused of extorting bribes from motorists while abandoning their duty of maintaining security.

Their failure in handling issues like militancy often forces the government to draft in soldiers to help them in operations.
