Danish police said there was no trace of a missing Swedish journalist inside an amateur-built submarine that sunk off the Nordic country’s eastern coast last week.

Copenhagen police spokesman Jens Moller Jensen said investigators uncovered no trace of 30-year-old freelance journalist Kim Wall in the UC3 Nautilus sub, which was raised and transported for investigation on Saturday.

Police will now continue to search for Wall in the waters near the island in Copenhagen’s harbour where the sub’s owner Peter Madsen allegedly dropped her off late Thursday.

Madsen made a last-minute escape from the sinking sub and has denied any responsibility for the fate of Wall. He was arrested on Friday on preliminary manslaughter charges.

Mr Moller Jensen said there are indications that the Danish inventor deliberately sank his submarine.
