Boko Haram's threat letter to NLC/TUC; real or fake?

 

According to the leadership of the NLC and TUC, they received a threat letter in their mail on Teusday supposedly sent by Boko Haram. In the letter (above), the Islamic sect expressed their anger over the way the Labour leaders handled the fuel hike crisis. They asked the NLC president to resign and also threatened to bomb their HQ soon.

The letter reads 'I', 'AM' instead of 'WE'...probably a prank but the NLC people are taking it very seriously. They've handed the letter to security agencies.

If this Boko Haram menace wasn't such a sad thing for Nigerians, I would have laughed at this letter. But....
