"His death is not being treated as suspicious and a file is now being prepared for HM Coroner. Tributes have been laid in the local area, and we ask that they are placed on the grassy area next to the Trent Port pub.
"Our thoughts are with Oliwier’s family at this incredibly difficult time. They are being supported by specialist officers and we ask that their privacy is respected. We also ask that people do not speculate about how or why Oliwier died."
On Thursday, police confirmed they believed Oliwier had entered the water after retrieving CCTV of him near the riverbank.
Superintendent Phil Baker said previously: “The last three days has seen a significant round-the-clock effort to find Oliwier.
"This has included searching abandoned buildings along the River Trent where he was last seen, searching footpaths, undergrowth, and local farmer’s fields, as well as speaking with friends, family, and his school, and reviewing CCTV footage and social media accounts.
“Having carefully pieced together Oliwier’s movements since he was last seen on Monday evening, we are now in the sad position to say that we believe he has entered the water.
"We have come to this belief after viewing CCTV footage which shows someone entering the water near the riverbank at The Flood Road bridge in Gainsborough at around 9.20pm on Monday.
"This is around the same location and time we had a last confirmed sighting of Oliwier.
"Because of this, we are now treating this as a recovery operation, and focusing our efforts in the water and along the water’s edge."
Supt Baker also thanked the local community who had been walking the river banks and locations around the River Trent as well as printing out posters of the teenager.
He added: "We would like to recognise the enormous support shown by the local community, which has included sharing information and local searches."
