The police were notified at 08.22 on Saturday.
– All three emergency services moved out. The first patrol from us got the person on land and implemented cardiopulmonary resuscitation. But the person was confirmed dead by ambulance when they arrived at the scene, says operations manager Christian Krohg Engeseth to NRK.
The person was found at Gullhaug bridge in Nydalen.
– We have a certain idea of who the person is, but do not want to go out with gender and age at the moment, says Krogh Engeseth.
Relatives have not been notified.
