A week after a York teen disappeared, his mum's made a fresh appeal to trace him.

Jordon Sullivan was last seen on the banks of the River Ouse on Valentine's Day.

The last sighting of him was early in the morning last Tuesday by a local resident living near the River Ouse.

They described seeing him stripping off naked and running towards to water.

He hasn't been seen since; and underwater and land searches have lead to nothing.

Now, 7 days on, Jordan's mum Nicola has launched a fresh appeal to trace him.

In an emotional press conference on the banks of the River Ouse in Bishopthorpe, Nicola started her appeal by repeating Jordan's name over and over:
