Purpose of double が in article title


I started to read this
[artcle](https://www3.nhk.or.jp/news/easy/k10012333031000/k10012333031000.html
"article") and I noticed there are 2 が particles in the title

> ２０００人以上の子ども **が** インターネット **が** 原因で犯罪の被害

If the first が marks the 2000+ children as the subject, what is the purpose of
the second が?




This is not a double が because each occurrence actually belongs to a separate
clause.

The first が indeed tells us that the subject of the main clause is
２０００人以上の子ども.

However, the second が belongs to the phrase インターネットが原因で "As a result of the
Internet", and tells us that the subject of _that_ phrase is インターネット "the
Internet".

Note that by omitting the phrase インターネットが原因で,

> ２０００人以上の子どもが犯罪の被害

we see that the true subject of the main clause is ２０００人以上の子ども.
