A 15-year-old boy has been arrested and charged over a spate of armed robberies on pizza delivery drivers in Sydney's west.
Police say he was allegedly involved in a string of heists between August 5 and October 3 with a 19-year-old man as they targeted drivers taking pizzas to houses in Cartwright and Mt Prichard.
They were both arrested on Thursday.
Police will allege that during each robbery, pizzas were ordered over the phone but random delivery addresses were given.
It is alleged they waited for each delivery driver to come to the house before committing the robberies and running from the area.
On each occasion they allegedly used either a knife or a firearm to threaten the victims.
The 19-year-old man was charged with three counts of armed robbery and was given conditional bail to appear in Campbelltown Local Court on January 18.
The 15-year-old male was also charged with three counts of armed robbery and was refused bail to appear in Campbelltown Children's Court on Friday morning.
