Just wanted to present an observation that Deutsche Welle (DW) has an extremely biased opinion of India and presents only the bad and sensationalized articles about things in India. As an Indian living in Germany, I have seen firsthand how misrepresented India is in foreign publications.
Although, I don't doubt the article, I would suggest you take the article with a pinch of salt. Yes, there are problems in some parts in India, but the foreign media portray it like people are running around killing and raping people, which is definitely not the case.
