Manchester United reportedly suspends Mason Greenwood as he is arrested on suspicion of rape and assault
Greenwood, 20, remains in custody for questioning and enquiries are ongoing, Greater Manchester Police said.
The force launched an investigation after being made aware of the images and footage earlier on Sunday.
It comes after Manchester United announced that Greenwood would not return to training or play any matches "until further notice" after he was accused of assaulting a woman.
The allegations were released on Instagram on Sunday morning and included video, photographs, and a voice note claimed to be a conversation between Greenwood and the woman. They have since been deleted. Read here
Manchester United said in an earlier statement:
"We are aware of images and allegations circulating on social media.
"We will not make any further comment until the facts have been established.
"Manchester United does not condone violence of any kind."
