Striker Tom Meechan has agreed to join the club for the 2018/19 season.
Meechan is well known to Martyrs fans having played for St Neots Town, where his goal scoring exploits earned him a move to Newport County. He also had spells at Weston Super Mare and Hungerford Town before returning to St Neots.
Manager Gavin Williams said "I am delighted that Tom has agreed to join us. He knows the Southern League well and is a proven goalscorer at this level and will strengthen the squad ahead of the season."
Meechan follows Kieran Lewis and Joe Perry as new signings ahead of the coming season.
