Barcelona condemned the “violent” mob that attacked Ronald Koeman’s car after the El Clasico defeat on Sunday.
Furious supporters stormed out of the Nou Camp as their side lost 2-1 to arch-rivals Real Madrid.
David Alaba and Lucas Vazquez scored for the visitors before Sergio Aguero’s first Barca goal was deep in injury time.
This made Koeman the second manager in LaLiga history to lose his first three Clasicos – and the first since Patrick O’Connell between 1935 and 1940.
And with many of the 86,422 fans inside the stadium already wanting the Dutchman to be sacked before the weekend’s defeat, minority protests turned toxic.
A clip posted online shows the Barca manager met with a large group of furious supporters who immediately spotted him and surrounded his vehicle.
Many of them started banging on the bonnet and windows of their Audi and insulted them while trying to force their way through the crowd.
On Sunday evening, Barcelona issued a strongly worded statement reprimanding the perpetrators.

It said: “FC Barcelona publicly condemns the violent and contemptuous acts that our manager experienced while leaving the Camp Nou.
Koman was clearly disappointed as Sergio Dest missed a brilliant opportunity moments before Alaba broke the deadlock with a sharp counter.
His side struggled to test Thibaut Courtois and Vazquez sealed the point as he slipped on a rebound in the 94th minute.
Aguero had time to return home three minutes later, but the Catalan giants slipped to ninth place, six points behind LaLiga leaders Real Sociedad.
The former Everton chief said after the latest setback: “I am disappointed with the result but the team tried till the last second.
“We didn’t create many clear opportunities. It was a similar match but the small details proved crucial in the end.
“It’s hard to find the positivity from losing at home to Madrid, but I liked the attitude of the players and the fans.
“There’s another game on Wednesday, the season is too long so we’ll keep fighting.”
