The bodies of three students of University of Port Harcourt (UNIPORT), kidnapped since 7 April, were exhumed by the police on Friday.
One of the bodies was that of a female student identified as Joy Adoki.
By the confession of one of the arrested kidnappers, she was gang-raped and then unconscionably hacked to death.
Police put all the three bodies in bags.

The other students were identified as Nelson Nwafor and Fortune Obemba.
All the bodies, including the dismembered Adoki were deposited later in the mortuary.
The police were able to crack the case after the arrest on 30 April of the chief suspect, called Friday Akpan.
He led them to the arrest of two other suspects.
Early on 1 May, he also took the operatives of the anti-kidnapping unit of the Rivers State Police Command to a forest at Eteo in Eleme Local Government Area.
There they found the bodies of the missing students.
It was learnt that the three undergraduates were kidnapped around Choba Campus of the University and driven to the forest.
Their abductors demanded ransom.
When the ransom was not forthcoming, the kidnappers, said to be members of the Iceland Cult, gang-raped Joy Adoki.
They thereafter butchered her to death.
According to DSP Nnamdi Omoni, the Police Public Relations Officer, exhibits recovered from the suspects include an AK47 rifle, three magazines and 72 rounds of ammunition.
The Commissioner of Police, Joseph G Mukan has assured the families of the deceased students that justice will be brought to bear on the culprits.
