An unidentified arm found by divers in the water near Copenhagen could belong to Swedish journalist Kim Wall who died after taking a submarine ride with the vessel's Danish inventor in August, Danish police said on Tuesday.

The arm was found near the route that had been investigated in connection with the submarine case, the police said in a statement. The limb would be examined by coroners on Wednesday.

"We have not yet determined if this is a right or left arm or who the arm belongs to. But we are working from a perspective that it stems from the submarine case," police spokesman Jens Moller Jensen said.

Wall, a freelance journalist who was researching a story on submarine owner Peter Madsen, went missing after he took her out to sea in the 17-meter (56-foot) submarine in August.

On Aug. 23, police identified a headless female torso that washed ashore in Copenhagen as that of Wall. In October, police said they had recovered her head and legs.

Danish inventor Peter Madsen is held on preliminary charges of manslaughter and indecent handling of a corpse for disposing of the body of reporter Wall who he claims he didn't kill. He has said Wall died inside the submarine while he was on deck. However, he has admitted throwing her body parts into the sea.
