Graham, 25-years-old, joins the Clarets on an initial one-month loan from Ebbsfleet United after signing for the Vanarama National League side from City at the end of last term.
Bagasan first signed for the Clarets in July 2013 under Dean Holdsworth, with the tricky winger being labelled as "an exciting player with huge potential." Since signing for Chelmsford four years ago, the former QPR trainee became a fan-favourite at the Melbourne Community Stadium with his pace and crossing ability from the wide position, Graham put the City ahead in last term's 2-1 play-off final defeat at Ebbsfleet United.
Graham now returns to Essex for a third spell with the Clarets, with the winger amassing over seventy appearances for City between 2015 and 2017, and is available for City's league tie at home to Hungerford Town this Saturday.
Everyone at Chelmsford City Football Club welcomes Bagasan Graham back to the Melbourne Community Stadium and looks forward to seeing him action this weekend.
