A boat carrying some policemen reportedly travelling to the southern Ijaw Local Government Area of Bayelsa State to monitor the senatorial bye-election, has capsized.
Although the police authority is yet to confirm the number of victims, at least three policemen are said to have drowned.
Bye-elections are currently holding in 11 states across the country, covering six senatorial districts and nine state constituencies.
In Bayelsa, election was being held in two Senatorial districts to fill the vacant positions created by Governor Diri and his deputy.
While Lagos and Cross River are the only states where both senatorial and state assembly elections are being conducted, the other nine states are either holding senatorial or assembly elections.
INEC had postponed the elections earlier scheduled for October 31, following the #EndSARS protests and other security and environmental challenges.
