A man is facing a murder charge for allegedly stabbing to death a man during an argument in Sydney's northwest.
Nathan Chatimba, 31, is accused of fatally stabbing the 34-year-old man outside a house at Dutch Place in St Clair about 6.40pm on Saturday.
Police allege the two men - who were known to each other - were arguing in the front yard of the St Clair house when Chatimba attacked the older man.
Chatimba also allegedly assaulted a woman, but it's unclear if this happened before or after the stabbing.
Two hours later, Chatimba was arrested at a home some 2km away and was charged with murder and assault occasioning bodily harm.
The matter was briefly mentioned at Parramatta Bail Court on Sunday where Chatimba, through his Legal Aid lawyer, did not apply for bail and it was formally refused by Magistrate Lyon.
He is due back at Penrith Local Court on October 12.
