It was a sombre homecoming for Abdul Abu-Mahmoud as he returned to Sydney from Thailand on Thursday and into the waiting handcuffs of homicide detectives at the airport.

The 33-year-old returned to Australia of his own accord after a warrant was issued for his arrest last month over the death of Sydney teenager Brayden Dillon, who was shot in his bed on Good Friday last year.

The teenager was asleep at 6am on April 14 when a masked intruder allegedly forced his way into the family's Glenfield home and fatally shot the 15-year-old.

Four people have previously been charged over the shooting. They remain before the courts.
