Who knows what happened to this man to send him into such an anti-Apple rage?

Maybe he bought a brand new iPhone 7 only to discover that it doesn't have a headphone jack.

Perhaps he'd had some kind of tech glitch that sent him over the edge - or a message on a dating app that sent him into a meltdown.

Or maybe he just really hates the company.

F or whatever reason, the unknown unhappy customer decided to let loose with a metal ball in a French Apple store, calmly and methodically smashing up every iPhone in sight.

Untroubled by security for some time, the man - wearing sunglasses and a backpack - used what appears to be a metal pétanque ball to cause the damage.

The man muttered angrily in French as he battered the phones on display in the Apple store

The identity of the man is not yet known.

The vandal seemed untroubled by the prospect of getting caught. His motives were unclear

The store was quiet at the time, but there were plenty of phones on display for him to bash up

It is also unclear exactly where the incident took place or if he was arrested. Bizarrely, it looks like he was just allowed to walk out of the shop, which some Twitter users have suggested was in Dijon.

The video proved a hit after being posted to Twitter on Thursday afternoon and has already received more than 4,000 retweets.
