A baby moose has been rescued from what police described as “a sure demise” after it fell into an Alaskan lake and became trapped between a seaplane a dock.

Tourism company worker Spencer Warren had arrived at work about 6.30am in the US state on Friday to prepare the floatplane for a day trip when he heard what he thought was an odd-sounding bird.
