A fatal overdose in an inner city laneway has led to a manslaughter charge against a man alleged to have administered the drug.
The 37-year-old was arrested at an address in Parramatta on Thursday following a months-long police investigation.
It comes after emergency services found a 45-year-old man unconscious in Parker Lane in Sydney's Haymarket around 5.20pm on April 1.
He was treated at the scene by paramedics and taken to hospital in a critical condition. More than two weeks later on April 19, police were informed the man had died.
Following extensive inquiries, investigators executed a search warrant and arrested the 37-year-old.
Police will allege in court that he administered the fatal overdose.
The man was taken to Parramatta Police Station where he was charged with manslaughter.
