Murder, cover-up charges for alleged drug deal stabbing

Police have arrested a man they say helped try to cover up an alleged drug-related murder, in an "awful" attack on a suburban street.

Officers found the victim, a man believed to be a Malaysian national aged 29, stabbed to death about 5pm on Monday at a home in Croydon Park, in Sydney's inner west.

Mohammad Sofwan Bin Mustafha, 32, has since been charged with murder and refused bail at Burwood Local Court.

Authorities then charged a second man on Tuesday night after he turned himself in at Burwood police station.

The 36-year-old man, who will face Burwood Local Court on Wednesday, was charged with concealing a serious indictable offence.

Superintendent Christine McDonald said the man was previously known to police and was on bail at the time of the alleged offending.

But she would not reveal the police's case as to how he had allegedly tried to conceal the murder.

"We are confident that he was at the scene at the time of the murder," she said.

"How the victim came to be at that location is still part of our inquiries but certainly we believe drugs were involved."

Supt McDonald did not detail why police believed the incident had stemmed from a drug deal.

The victim was repeatedly stabbed in the neck, with police initially estimating the man as aged in his 50s before they learned he was 29.

Police have spoken to the victim's family in Malaysia.

"All three men have wives and children," Supt McDonald said.

"We say so often that drugs ruin lives and families, and this is yet another example of wives and children getting caught up in an awful crime."

Bin Mustafha did not apply for bail when he faced court on Tuesday and will return to court on July 30.
