Striker Caluam Jahraldo Martin joins The Exiles from League One Oldham Athletic on a one-year deal.
The 24-year-old striker began his career at Boreham Wood FC before moving to Dulwich Hamlet. His performances at Dulwich caught the eye of Hull City FC who signed the young striker in 2013.
After impressing in Hull's Academy, Calaum featured for the first team before heading out on loan to Tranmere Rovers and Leyton Orient. He was snapped up by League One Oldham Athletic in 2015.
Calaum joins The Exiles on a one-year deal.
Manager Michael Flynn said: "Calaum deserves this contract. He's been on trial at the Club for a month and has done everything in the right way since being here. He's done really well in training and has performed well in the pre-season games he's played for us. Calaum will add pace, energy and competition at left back."
Calaum is speaking exclusively to iFollow Exiles tomorrow and the interview will be online tomorrow.
We begin the 2017/18 Season on Saturday with a
trip to Stevenage FC.
