JAKARTA:- A group of suspected animal traffickers have been arrested in Indonesia for selling crocodiles, pythons and other protected species through Facebook and the messaging service WhatsApp, police said Wednesday. The case is the latest example of how social media has become a key online market place for animal traffickers as conservationists warn that tech giants have not done enough to halt the trade on their platforms. The seven suspects, who were arrested at separate locations in and around Jakarta last week, bought the animals for just 300,000 rupiah ($22) each before re-selling them online for between two million and five million rupiah, authorities said.
