Amarildo was last seen at his home address in Radlett, at 10.45pm on Tuesday, February 6.
Update: Amarildo has been found safe and well, according a police statement on March 23.
Officers have now appealed for the public's help in finding the teenager.
A spokesperson for Hertfordshire Constabulary said: "He is described as around 5ft 8ins of slim build with short dark brown hair, with a moustache.
"Amarildo is believed to be wearing a dark tracksuit and dark jacket and trainers.
"If you have information, you can report this by calling 999 immediately if you believe you are with him now, or have seen him in the last few moments."
