PARIS (AP) — The director of a group that advocates for female sports fans says she and other Paris Saint-Germain supporters were subjected to “abusive” searches while entering Barcelona’s stadium for a Champions League match earlier this week.

Anoush Morel, the director of Her Game Too France, told L’Equipe and RMC Sport that her breasts, buttocks and groin were touched by a female security officer during a pat-down at the Lluís Companys Olympic Stadium on Tuesday night. Other women reported similarly aggressive searches, she said.

Paris Saint-Germain won the match 4-1 and advanced to the Champions League semifinals.

In a letter Thursday, the organization condemned the practice and called on “relevant authorities” to take action.

“It’s unacceptable that spectators, fans and women in general were particularly targeted by these intrusive and humiliating searches that constitute sexual aggression,” the letter read.
