Andre Boucaud said his goodbyes at the training ground on Thursday before heading to Notts County to complete his move to the Magpies.
The midfielder, 28, left the club's headquarters in Ely Way with a carrier bag of possessions at around 12.45pm after bidding farewell to the club's football staff.
He walked out with Scott Neilson, who joined earlier this month from Crawley Town, shook hands with the winger before driving off in a silver Audi A3.
"Boucaud has left now," Alan Neilson said. "Gary Sweet [the managing director] and the gaffer sorted it all out and I think all parties are happy. We wish him all the best and I'm sure he wishes us the same."
The Enfield-born man joined from York City less than a year ago but he has not played for the Hatters since April, when he came on as a 60th-minute sub against Alfreton, and has fallen out of favour with Paul Buckle. He managed to secure a loan move to Notts County and Buckle hinted in November Boucaud may have to sacrifice some money to turn his loan move to the League One club into a permanent one.
"Some players knock on the door when they are not playing and say they are willing to give up money and then move on," Buckle said in November. "But that wasn't the case."
Luton paid York £25,000 for Boucaud last year and although the fee Notts County have paid is undisclosed, the Hatters say they have not recorded on a loss on the player.
“We’ve surpassed that (£25,000 plus add-ons depending on Luton’s performance last year and this year), so from that perspective, although it will be an undisclosed fee, I think we can all see that we’ve at least broken even with Andre," Sweet told the News/Gazette.
