Streaker invades Darwin Cup track

A streaker achieved fleeting but costly fame after sprinting naked onto the track at the end of the main race at the Darwin Cup.

The unidentified man was captured on camera evading security guards before eventually being tackled as he tried to leap into the VIP tent.

He copped a heavy fine from police, the Northern Territory News reports.

The naked dash was one of several examples of rowdy behaviour as boozed-up patrons enjoyed the Cup.

One man was caught trying to climb up a giant television screen, while a kilt-wearing man was snapped showing off his privates in full public view.

But Darwin Turf Club executive director Des Friedrich told the newspaper there were only a handful of troublemakers among the 25,000 people who attended the event.

"I'm unaware of any serious altercations," he said.
