Barnet's player of the season Joe Devera has rejected a new contract offer and agreed a move to League Two rivals Swindon Town.
Lawrie Sanchez offered a contract to the 24-year-old this summer but he has decided to join Paulo Di Canio's side.
The 24-year-old central defender or right back, who was also voted the most improved player by members of Barnet FC Supporters Association, made 190 starts for the Bees and ten substitute appearances.
His departure is a blow to Barnet and Sanchez will be keen to replace him over the coming weeks.
