A man armed with AK 47 rifle was killed and his accomplice escaped while three residents of Federal Low Cost Housing, Bauchi, were injured following a suspected armed robbery attack on Wednesday.
The incident occurred in the early hours when civil servants and other residents of the area were going to their places of business.

The source, who wants to remain anonymous, further said that the attacked policeman escaped and the suspected robbers later attacked and injured three civilians resident in the area.
