Stevenage have completed the signing of former Yeovil Town defender Bondz N'Gala on a two-year deal.
The 22-year-old only spent a single season with the Glovers following his move from Plymouth in 2011.
N'Gala also worked with Boro's assistant manager Mark Newson during their time together at West Ham.
"He is a dominant centre-half. He's big and strong and was my captain in the two years I spent working with him," Newson told the club's official website.
"He's a great leader and always works hard for the team, so I'm delighted to be working with him again."
