Igor, 42, thought he was a goner when the brown bear pounced on him as he was walking to a favourite fishing spot in northern Russia’s Yakutia Republic.
But as the bear began to claw at him, Igor’s mobile went off and the beast turned tail and fled back into the forest.
Wildlife experts believe the ringtone – according to local media the singer’s hit ‘Baby’ – must have startled the bear into halting its attack.
“Sometimes a sharp shock can stop an angry bear in its tracks and that ringtone would be a very unexpected sound for a bear,” explained one.
Igor suffered from cuts and severe bruises to his face and chest and was rescued when he was found by other fishermen after using the phone to call for help.
