The mother of 13-year-old Arthur Haines, who police allege was murdered in 1998, says she's ecstatic police have arrested a suspect 24 years later.
"I couldn't believe, in the sense of, finally today is the day that they have got somebody for Arthur," Julie Szabo said outside Surry Hills police station in inner Sydney on Friday.
NSW Police allege the man escalated a neighbourhood dispute by recklessly throwing a petrol bomb into a Waterloo home where Arthur and other children were sleeping on April 9, 1998.
