Trio charged after man shot in Sydney

Three people have been arrested after a man showed up at a Sydney hospital with a gunshot wound to his leg.

Police were called to Nepean Hospital about 9.45pm (AEDT) on Monday after the 34-year-old received treatment for the injury.

A crime scene was later established at a hotel on Mulgoa Road in Penrith, where police believe the shooting occurred.

A 40-year-old man and 25-year-old woman were arrested at the hotel and have since been charged with hindering a police investigation.

A 28-year-old was also arrested after officers raided a Penrith home, where police say they seized a firearm.

The man has been charged with discharging a firearm with intent to cause grievous bodily harm.

The trio were refused bail to appear before Blacktown Local Court on Tuesday.
