Bangor finally laid that Jenner Park bogey to rest and in so doing drove another nail in the coffin of the cash strapped - and disgraced - reigning champions.
The home hero was a debutant 28-year-old goalkeeper Quinn McCarthy, signed from Cardiff Corinthians, who gave an impressive performance to rival those of the long departed Mark Ovendale.
But it was the home side who made a good start and former Cwmbran striker Mattie Davies had the ball in the net, but the linesman had already flagged for offside. After some early nerves City began to get a grip, with Owain Jones showing well in midfield and the movement of top scorer Paul Gedman unsettling the new look Yellow Dragons defence.
It was fitting then that the former Cefn Druids striker was the man to break the deadlock on the half hour after he was fouled by Rees. A low driven freekick from the right, propelled goalwards by Ricky Evans, was guided home by Paul Gedman from close range to the delight of the three dozen or so travelling blues.
The goal boosted the Bangor side who ended the half comfortably on top.
The second half saw Bangor in control, but McCarthy and the home defence, marshalled by former Newtown defender Adam Shakespeare, perform heroics. Fifteen minutes into the second period Clayton Blackmore replaced right winger Kenny Burgess, with Peter Hoy moving to sweeper in a 3-5-2 formation.
Workaholic striker Lee Hunt doubled the lead on 62 minutes with an tap in from a Clayton Blackmore cross which was flicked on by Paul Gedman.
On 66 minutes it was all over as Paul Gedman was fouled in the box to allow Ricky Evans to convert the penalty kick and complete the scoring. With the result beyond doubt, City sent on Gary Roberts for Gareth Williams and then ten minutes from time Ricky Evans made way for Ross Jefferies.
City continued to create chances, Lee Hunt and Owain Jones hit the woodwork, but McCarthy continued to work overtime and his defence rode their luck.
