Two teenager boys/two young boys, were arrested over a robbery in Arapongas.
(in journalese of now that the two were arrested on suspicion of ...or charged with... )
In America, though, they usually don´t have any qualms of divulging name and age in news items:
[/url]Josue Fuentes-Ponce, 16, Joel Escobar, 17, and Cynthia Hernandez-Nucamendi, 14, are suspected of killing Funes-Diaz in a wooded area behind an apartment complex on 64th Avenue on April 18, Prince George's County police said in a news conference Thursday.
So, in that case (and with aN English-culture ring to the item) it would be:
"26-year-old João das Quantas and 25 y.o. Paulinho Anonimato were arrested, charged with..."
Or something like that.
