Hatters defender Steve McNulty has completed his permanent move to National League side Tranmere Rovers.
The 32-year-old moved to Prenton Park on loan in October and has made 12 appearances so far, scoring his first goal during the 2-1 win at Macclesfield Town on Boxing Day.
McNulty, who played 125 times for Luton, scoring two goals, has now penned a deal until the end of the 2016-17 season.
Tranmere boss and former Hatters manager Gary Brabin told the Rovers’ official website: “I’m really pleased that we’ve agreed a permanent deal with Steve to remain at the club.
“He’s a leader, has experience of promotions out of this league and has done really well in the couple of months that he has been here. He has settled in nicely with the rest of the squad and I’m delighted to extend his stay at the club.”
