Meanwhile, the recent upsurge in violent killing in Yenagoa and its environs is gradually crippling night life in the Bayelsa State capital as most residents are now compelled to retire home early.
This was the scenario about three years ago when the then bubbling night life in the capital city was almost grounded in the wake of the violent clashes between suspected rival cult gangs who held the state capital hostage.
No fewer than six persons have been reportedly killed in the last four weeks in separate attacks in different parts of Yenagoa and its environs by unknown gunmen.
