The Special Commissioner of Dabanga (Far North), Ismaila Sago, has been summoned by the Cameroonian army for questioning in Yaounde, military sources told Xinhua on Tuesday.

Ismaila Sago was initially a hostage of Boko Haram after an alleged attack, of which he had been the main target on January 4.

"He is suspected of collaborating with the enemy and is currently under interrogation in Yaoundé," the source said.

Back from a trip to Kousseri, Cameroon border town with the Chadian capital N'Djamena, the police officer was attacked on January 4 in the afternoon by an armed group believed to be affiliated to Boko Haram. He was on his way to his workstation in Dabanga, on the border with Nigeria, in the Far North region.

He was on board in his company car which also carried three other people, including a retired police inspector and two civilians who were abducted with him by unidentified assailants group. The vehicle was recovered close to where the presumed attack took place.

In reality, Ismaïla Sago was arrested during a special operation of the Rapid Intervention Battalion (BIR), a special force of the Cameroonian army engaged with other units of the defense and security forces in the fight against Boko Haram.

Ismaïla Sago is not the first police official targeted by such accusations. Other names had already been mentioned earlier in unauthorized press educated trial by the military courts of Cameroon.

Meanwhile, a Far North district sub-prefect is also stated in the viewfinder of justice services for the same reasons. He is been accused of intensifying massive armed attacks, and unclaimed suicide attacks which the security services attribute to Boko Haram.

Since 2013, nearly 1,200 people, including 67 soldiers were killed in some 315 incursions of Nigerian armed group in Cameroon, according to official estimates.

Many times, the President of the National Assembly (lower house of Parliament), Cavaye Yéguié Djibril, has stepped into the breach to denounce, without naming them, "accomplices" found within the countries of the nebula.
