au.fourfourtwo.com yesterday revealed how the Jets owner had blown his top over a protest by disappointed members of Jets fan group the Squadron.

They had hung their banners upside down at the weekend's game against Perth Glory in a show of disgust at Newcastle's woeful defence of the Championship this season.

But security were ordered to take down the banners midway through the first half, and Squadron ringleaders were summoned to Con's private box for a furious tongue-lashing from the owner.

As well as a tirade of abuse, Con allegedly threatened to chuck Squadron president Tim Verschelden off the balcony at EnergyAustralia Stadium.

Yesterday the FFA said they were aware of the incident and would be investigating.

Now Con's confessed to the outburst, but says he has no regrets and claims the protests "killed the credibility of the club".

"When you're upset with someone you say a lot of things," he told The Sydney Morning Herald.

"I swore at them because I knew they were wrong. At the end of the night Timmy and his family came back to the club, so he obviously didn't take it too badly."

He added: "If they think for one minute that I'm happy that I got the wooden spoon, they should know I'm a bad loser.

"If they have an issue with the club they could have come and addressed it with me."
