This led to a security beef up around the presidential villa and other strategic government buildings and locations in the Federal Capital Territory.
Spokesperson of SSS, Marilyn Ogar who confirmed this in a statement said one of the suspects attempted to disarm one of the officers who has gone to feed the inmates.
The statement said the officers in the process fired some shots in the air.
It said three other detainees who sustained gunshot injury during the process have also died.
