At Ossemotor in Oguta local government, voting ended around 3.40 p.m. while counting commenced immediately while it ended in most other places around 5 p.m.
The election has been characterised by violence and other electoral malpractice, especially in Oru East local government.
The election is holding in some polling units in 23 local government areas which were cancelled or inconclusive in the April 11 election.
Meanwhile, a chieftain of the Peoples Democratic Party, Mr Marshall Anyanwu, complained that there were too many unaccredited observers at the election, especially in Omuma, Oru East local government.
Anyanwu, a former chairman of APC in the state, told newsmen at the Omuma Central School that state government officials, posing as observers, were all over the place in contravention of the electoral law. (NAN)
