Andrew Symonds brings down the streaker © AFP

When the spectator ran near Symonds, the batsman moved across and bumped into him in a shepherding action more familiar to the Brisbane Lions Australian rules team when it plays at the Gabba. The force of Symonds' shoulder sent the man to the ground and security and police swarmed before taking him from the field.

Symonds, who sometimes trains with the Brisbane Broncos rugby league team, remained unflustered and went to talk to his partner Matthew Hayden. The ICC's Level 4.2 regulation covers "physical assault on another player, umpire, referee, official or spectator", but it is highly unlikely Symonds will be punished. The streaker faces a maximum fine of A$3000 for the ground invasion and police also intend to charge him with willful exposure.

"I'd just got out, so I was sooking," Ricky Ponting said. "I haven't seen it yet, there's been a bit of talk and laughter around the dressing room, but I haven't spoken to Symmo about it."

Another naked man ran towards Harbhajan Singh later in the innings but turned away before reaching the offspinner. This time the players let the security guards take care of the offender.

Symonds is not the first Australian to have had an altercation with a spectator. Greg Chappell once whacked a streaker on the backside with his bat after the man ran on to the field and shook the batsman's hand. Terry Alderman, the former Australia swing bowler, was less fortunate than Symonds when he tackled an English fan during the 1982-83 Ashes series, dislocating his shoulder and not playing a Test for 18 months.
