Unfortunately, he did not survive. The incident took place in Wale's Brecon Beacons mountain range this past weekend, where another man was also hit by lightning and died as well.
It is still not 100% confirmed that the man was holding the selfie stick when the lightning hit him, but it is quite likely. Perhaps this is a sign that selfie sticks should be banned from the planet. It could also just be a warning against holding anything metal during a storm.
