West Ham United can confirm that midfielder George Moncur has joined Colchester United on a permanent basis for an undisclosed fee.
The 21-year-old has been with the U's on loan since pre-season, making 21 appearances and scoring three goals in all competitions.
Moncur, who joined the Hammers as a teenager, departs the Boleyn Ground after making two first-team appearances for the Club.
The son of former West Ham favourite John, Moncur made his debut as a substitute in a League Cup tie against Crewe Alexandra in August 2012 and his first and only start in an FA Cup third-round match at Nottingham Forest in January 2014. During his time at West Ham, he also made more than 50 Development Squad appearances and enjoyed loan spells with AFC Wimbledon and Scottish side Partick Thistle.
On his departure, Moncur thanked the Hammers for the support the Club gave him during the early part of his professional career.
"There is some sadness about leaving West Ham because I was there for a good few years and I had some great times there," he said. "My Dad spent a few years there as well so I'll miss it but I've got a new challenge in front of me now. I have got to thank the people at West Ham, especially Nick Haycock and Ian Hendon who spent a lot of time with me and improved my game.
West Ham United would like to thank George for his hard work and commitment and wish him all the very best for his future career.
