The athlete celebrated his 18th birthday with a party attended by his teammates and other celebrities 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.

Performers defend their presence at the footballer’s 18th birthday and reject a statement made on their behalf by a disability rights group.
