A 15-year-old boy in Russia’s Altai Republic reportedly survived a bear attack after the animal bit his smartphone, causing its battery to catch fire and scare the predator away.

The teenager was in a remote area with a friend when they encountered the bear. He tried to escape by climbing a tree, but the animal knocked him to the ground and attacked him, according to SHOT.

During the attack, the bear bit the teenager’s smartphone. The battery then ignited, prompting the animal to flee.

The teenager was taken to hospital in serious condition, while his friend was unharmed. Hunters are now searching for the bear.
