Bradford City overtook Barnet to move up to 18th in League Two with a convincing away win at Underhill.
The Bantams went a man and a goal up in the 17th minute when Darren Dennehy was sent off for fouling Marcel Seip and Craig Fagan scored the penalty.
Will Atkinson doubled City's advantage when he clipped home Kyel Reid's cross.
Reid jinked through the Bees defence to score a goal of his own and Nahki Wells rounded goalkeeper Liam O'Brien for a late fourth.
Bradford are now two points above the Bees and eight clear of the relegation zone.

Bradford City manager Phil Parkinson told BBC Radio Leeds:
"I'm very pleased. We started the game very well and our forward play was very good.
"We made it look simple because the defenders defended properly and did their jobs and we passed it well and that make us look strong.
"We looked a good, solid, professional side and that's very pleasing."
