Dagenham notched a fifth successive win as they beat Bradford.
An unmarked Mark Arber headed the visitors in front before City should have levelled when they were awarded a controversial penalty.
Ross Smith was adjudged to have fouled Willy Topp but Barry Conlon saw his spot-kick saved by Tony Roberts.
Arber threw himself in front of Alex Rhodes to stop him firing in the rebound before a close range Ben Strevens strike secured Dagenham's win.
