Video footage posted to social media appears to show the music star being detained, as a voice is heard saying: “Are you serious? What the f***?”.

It came after the 48-year-old stormed the rap category, taking home best rap album for his sixth studio album, Michael, while his track Scientists And Engineers featuring Andre 3000, Future And Eryn Allen Kane won best rap song and best rap performance.

A spokesperson from the Los Angeles Police Department told the PA news agency that a man was arrested at the awards ceremony, but declined to provide their identity.

“Just after four o’clock this afternoon, a male adult was detained by police for a physical altercation that occurred inside the Crypto arena,” the spokesperson said.

“They handcuffed the individual and they removed them from the event and he is currently being questioned by authorities.

“If the individual is booked and arrested, then that’s when the identity will be available on that individual.”

The US star celebrated several Grammy wins on stage during the pre-telecast ceremony.

“This is for all the people who think you’re too old to rap … we keep hip hop alive. Never ever stop doing what you do.”

He later added: “You cannot tell me dreams do not come true.”

The excitement started early with Kylie Minogue winning her second ever Grammy. Minogue won best pop dance recording for Padam Padam – her first Grammy win in 18 years.

Billie Eilish and Finneas arrived early to collect their trophy for best song written for visual media, awarded to the brother-sister duo for their “Barbie” ballad What Was I Made For.

“This is shocking to me,” Eilish said. “I was expecting to turn right back around and leave.”

“I want to thank our parents, our dad, who worked as a construction worker at Mattel Corporation for much of our childhood to keep food on the table,” Finneas said.

The Beatles also won best music video for the animated clip for I’m Only Sleeping.
