Two fishermen disappeared from their fishing boat and the empty boat was later found in the lake of Hjalmaren in east Sweden, local media reported on Sunday.
The empty boat was found by a local and the two missing men were said to have set off to empty their fishing net on Sunday afternoon, according to the Swedish daily Dagens Nyheter (Dn).
The weather was good and the search for the missing two has already started, in which rescue helicopter, hovercraft and over 10 boats have joined.
"We have dog patrols and policemen searching on the islands where the men are likely to get to," Per Nellberg from the local police was quoted as saying by Dn.
According to the police, the rescue is also taking place on some smaller islands.
However, so far there has been no track of the missing men, said Dn.
