Four Moree men have been charged with murder as part of an ongoing investigation into the death of a Sydney man last year.
The state's homicide squad have been investigating the bashing death of 42-year-old Vergel Velasquez, who died in a Sydney hospital a day after being found with severe head injuries in a stairwell of a Girraween unit block on December 30.
Strike Force Brallo was established by homicide squad detectives who executed search warrants at units at Granville and homes in Moree earlier this year as part of the ongoing investigation.
A 49-year-old man was arrested by strike force investigators on Thursday, May 14. He was charged and remains before the courts.

All four men were taken to Moree Police Station and charged with murder.
They were all refused bail to appear at Inverell Local Court on Wednesday, June 24.
