WA Police investigate shooting at Kwinana Motorplex in Perth
Gang Crime Squad officers are investigating an overnight shooting at Kwinana Motorplex, south of Perth.
Police said officers were called to the motorsport venue at about 8:30pm.
Two patients were treated at the scene by paramedics.
One was rushed to Royal Perth Hospital, while the other was taken to Rockingham General Hospital.
"Gang Crime Squad will be working throughout the night investigating this incident," Inspector Simon Hazell said.
In 2010, an argument between two bikie gangs erupted at the same venue and left at least two people injured, including one with a gunshot wound.
A number of gang members were later jailed by the Corruption and Crime Commission for failing to answer questions over the fight.
Inspector Hazell said anyone who saw the incident should contact police.
