Olympic champion Renaud Lavillenie won a third European indoor polevault title on Sunday, but was furious that a mighty 6.07m attempt was ruled out over a technical hitch.
The Frenchman took gold with 6.01m before successfully clearing 6.07m on his third and final attempt which would have made him the second highest vaulter in history behind the legendary Sergei Bubka.
But officials ruled his attempt was invalid as the bar had not been correctly installed on the pegs to hold it securely in place.
A furious Lavillenie kicked out at the advertising hoardings and launched an angry tirade against the judges before collapsing to the floor.
After a tense few moments, the French athlete reluctantly accepted the decision and celebrated his victory, achieved ahead of German duo, Bjorn Otto, who recorded 5.76m, and Malte Mohr, 5.76m.
Earlier, British hurdler Perri Shakes-Drayton continued to impress on the flat with a commanding gold medal run over 400 metres.
The 24-year-old, who failed by one place to make the 400m hurdles final at last year's London Olympics, powered home in a personal best 50.85sec, which was also the fastest time in the world this year.
The silver medal also went to Britain with Eilidh Child more than half a second slower with Sweden's Moa Hjelmer finishing strongly to take the bronze.
The men's 800m was won by defending champion Adam Kszczot of Poland in a time of 1:48.69, with silver going to Spain's Kevin Lopez (1:49.31) and the bronze to rising British star Mukhtar Mohammed in 1:49.60.
There was an upset in the women's 800m where, on the final lap, Ukraine's Nataliya Lupu burst clear of strong favourite Yelena Kotulskaya of Russia, with Marina Arzamasova of Belarus in third. Defending champion Jenny Meadows of Britain was fourth.
