They say that 'Town paid League Two Hereford a significant five-figure sum for the services of Stuart Fleetwood'.
Whatever the figure, Hereford United have sold one of their highest paid players.
Fleets was signed by previous manager Simon Davey from Charlton and it's believed that the striker took a substantial pay-cut to move to Edgar Street.
Meanwhile Fleets has tweeted this morning.
"Delighted to have signed for Luton Town! Too many people to thank @ HUFC, loved my time there and wish them every success this season!"
Finally BN, who have sponsored Fleets during both his spells with the Bulls, will look to move its sponsorship to another player. Hopefully a new deal will be confirmed with the club later today.
