NSW man found with serious injuries

Police have established a crime scene after a man was located outside a Macquarie Fields home suffering serious injuries overnight, NSW Police say.

About 10.30pm today, emergency services were called to a home on Saywell Road after a man knocked on the front door of the premises covered in blood and suffering serious injuries.

Police located the 32-year-old man slumped in a chair on the front porch of the home and was suffering stab wounds to his arm and leg, and appeared to have been assaulted with a blunt object.

The man was taken to Liverpool Hospital where he remains in a stable condition.

Officers commenced an investigation that led to a second crime scene at a home on Railway Parade, Macquarie Fields.

Inquiries are continuing.
