Home shooting leaves one dead, four seriously injured

A 28-year-old and a 32-year-old arrived at Liverpool Hospital about 8.30pm on Tuesday with multiple wounds.

While the younger man was treated for a gunshot injury, he died a short time later.

The 32-year-old is in hospital with a neck injury and remains in a serious but stable condition.

About 10 minutes later, two other men - a 23-year-old and a 22-year-old - presented to Fairfield Hospital in serious conditions before being moved to other hospitals for further treatment.

The 23-year-old received care for a gunshot wound to the neck and the other was treated for a shoulder injury.

The fifth man, a 19-year-old, arrived at Liverpool Hospital an hour later with injuries to his arm, and remains in a stable condition.

"Initial information indicates the men were all injured during a shooting at the home earlier in the night," NSW Police said in a statement.

Officers were seen swarming around the hospitals' emergency wards in the late hours of the night as an investigation was launched into the incident.
