The Scot was spoken to by police after claims made by builder Josh Gillibrand, 23, that he had been attacked at a wine bar in Clitheroe, Lancashire. Officers were called to the upmarket Emporium bar in the town following a report of the altercation on the evening of May 21.
It is understood Moyes, 51, had been socialising with his friend, Blackburn Rovers managing director Derek Shaw, a local businessman in the Ribble Valley.
Witnesses reported Moyes, who had been sacked by Manchester United the previous month, was abused by a group of drunken young men shortly before he entered the bar.
Mr Gillibrand, from nearby Dutton, denied that he or his friend were involved in the abuse but said he "felt like I was going to die", as trouble allegedly flared.
Police said at the time there were, "a number of differing accounts" of what happened.
Lancashire Police has now confirmed no further action will be taken against any party.
A spokesman said: "After careful consideration of all the circumstances in this case it has been decided that no further action will be taken against anyone."
