Barcelona soccer star Lamine Yamal is facing scrutiny after he allegedly hired people with dwarfism to entertain guests at his 18th birthday party on Sunday, July 13.

A Spanish government official has called for an investigation into Barcelona star Lamine Yamal’s 18th birthday party after a prominent disability activist group said organizers of the event hired people with dwarfism “solely for entertainment and attractions” in contravention of Spanish law.

Spain’s prosecutor’s office will investigate whether any laws were broken after claims that Yamal hired people with dwarfism to perform at his 18th birthday party
