It was learnt that the incident, which occurred about 8.30pm on Sunday, threw the police station into confusion.
The police sergeant, whose name has yet to be ascertained, was reportedly gunned down by the hoodlums who were on a motorcycle.
Sources claimed that the fleeing gunmen shot randomly at a group of policemen in the front of the station, but the bullet hit the sergeant, killing him. The hoodlums, said to be two in number, escaped.
It was gathered that the cop did not die instantly. He was said to have been rushed to the Sagbama General Hospital, where he later died.
The Police Public Relations Officer, Bayelsa State Police Command, Mr. Asinim Butswat, said the police had launched a manhunt for the killers.
Butswat said, “We are working to establish the motive behind the dastardly act because they didn’t stop. We recovered the rifle of the dead policeman. They shot at a group of policemen and rode off, but we have swung into action, while some people are helping with useful information”.
