Police are appealing for witnesses to a public-place shooting in Penrith yesterday.
About 6.15pm, a number of shots were fired at a white Toyota Hilux in the car park of the Nepean Village shopping centre on Station Street.
Police arrived a short time later and arrested a 24-year-old man inside the shopping centre.
During a search of the man and his belongings, police seized a loaded 9mm pistol and additional ammunition, along with an amount of a white powder believed to be amphetamine.
The man complained of chest pains and was taken to Nepean Hospital, where he remains under police guard.
Following inquiries, police later attended a home in Kyre Crescent, Emu Plains.
During an examination of a white Toyota Hilux at the residence, officers located what appeared to be a bullet mark on the bumper bar.
Police from Penrith Local Area Command are continuing their investigations into the incident, which they believe has links to outlaw motorcycle gangs (OMCG).
They are appealing for anyone who witnessed the incident or has relevant information to come forward. Information can be provided anonymously.
