Striker Sanchez Watt has completed a move to Colchester United on a free transfer.
Watt was released by Arsenal earlier this summer after failing to make a league appearance for the club.
The 22-year-old joined Colchester on a season-long loan last season, but his time at the Weston Homes Community Stadium was cut short through injury.
The former England Under-19 international scored twice in seven appearances for United during the last campaign.
