The Football Association of Wales has postponed a press conference on Tuesday following allegations against manager Ryan Giggs.
The Welsh FA issued a statement late on Monday night saying it was aware of reports involving Giggs but would not be commenting further.
Police have confirmed they were called to an address in Greater Manchester on Sunday following reports of a "disturbance".
"A woman in her 30s sustained minor injuries but did not require any treatment," read the statement.
"A 46-year-old man was arrested on suspicion of section 47 assault and section 39 common assault.
"He has since been bailed pending further enquiries. Enquiries are ongoing."
Giggs was scheduled to attend the news conference to announce the Wales squad for their upcoming games against the United States, Republic of Ireland and Finland.
Former Manchester United winger Giggs has been Wales manager since succeeding Chris Coleman in 2018.
Wales next face the United States in a friendly at Swansea's Liberty Stadium on November 12 ahead of two crucial games in the Nations League.
Group leaders Wales host the Republic of Ireland on November 15, before facing Finland on November 18 - with both games to be held at the Cardiff City Stadium.
