An investigation is underway after a man was stabbed in Sydney's west.
The man's housemates called an ambulance last night after the 33-year-old returned to his Lalor Park home with a stab wound.
Police say he left his house yesterday to go to the nearby Freeman Road shops, returning four hours later wounded.
He's undergoing treatment in Westmead hospital where his injuries are not believed to be life threatening.
Detectives want to speak to anyone who may know anything about the stabbing.
