Accrington thrashed Bradford and moved into the League Two play-off places.
Luke Joyce put Stanley ahead early on when he controlled and superbly curled the ball into the top corner.
Andy Procter drove in a low shot to double their lead, before poor defending allowed Sean McConville to tap in to make it 3-0 before the break.
Bradford's best chance came from James Hanson in the first half but he fired over the crossbar and they failed to trouble the Reds again.
Bradford City interim manager Peter Jackson told BBC Radio Leeds:
"The performance wasn't acceptable in the first half. The fans were right to sing what they were singing to the players, 'You're not fit to wear the shirt' and they simply weren't in that first 45 minutes.
"We don't want to rely on other results, we just want to rely on us winning games, picking up the points that we need.
"But as I say, we've got three games to do that and its still in our hands. Games are running out I know that but we desperately need that vital win on Monday."
