Manchester United footballer Mason Greenwood has been arrested on suspicion of rape and assault following allegations on social media.
Greater Manchester Police said it was made aware of "social media images and videos posted by a woman reporting incidents of physical violence".
It added "we can confirm a man in his 20s has since been arrested on suspicion of rape and assault".
He remains in custody for questioning and inquiries are ongoing.
United earlier said the forward would not return to training or matches until further notice.
The club said they "do not condone violence of any kind" and had been made aware of the allegations on social media but would make no further comment until the "facts have been established".
Nike released a statement, first reported in The Athletic, saying: "We are deeply concerned by the disturbing allegations and will continue to closely monitor the situation."
Greenwood has not responded to the social media allegations.
The 20-year-old, who made his United debut in March 2019, signed a four-year deal in February 2021 after rising through the ranks of the academy.
Greenwood apologised after being dropped by England manager Gareth Southgate for a breach of coronavirus protocols while on international duty in Iceland in September 2020.
A month later, his United manager at the time, Ole Gunnar Solskjaer, defended Greenwood amid media speculation of his being late for training.
