The OKO - meaning The Eye - is currently the tallest in Europe, at a height of 354 metres (1161ft)
The 18-year-old, named only as Alexander Sh, landed on a Mercedes G-Wagen parked below the 1,161ft OKO skyscraper in Moscow.
Russian reports gave two versions over the student's tragic fall from close to a skating rink high above the Russian capital.
As well as the selfie version of events, when he fell, others suggested that he had a furious row with his father before running to a rooftop helicopter pad and falling off.
The OKO - meaning The Eye - is currently the tallest in Europe, at a height of 354 metres.
A source from Moscow emergency service: 'A young man - 18 years old - fell from the 86th floor of the OKO tower in Moscow City.
The teenager landed on a Mercedes G-Wagen parked below the 1,161ft OKO skyscraper in Moscow
'He fell right on a Mercedes car that was left in the outdoor parking lot.
'One of the versions of what happened is that he tried to make a selfie.
'According to the building's security, the young man had been with his father at the skating rink.'
But news website Life.ru citing eyewitnesses said: 'People said there was an argument between the young man and his father.
'In the heat of the moment Alexander ran to a helicopter pad and jumped off.'
At least he had time to yell "Sorry."
And if he did it by accident, realize his stupidity;
And if on purpose; regret his apparent impulsiveness.

P.s., Please realize that of all the accidental deaths and suicides in Europe this day, you are ONLY aware of this one because it happened to occur on the tallest building.
