Obviously we have very limited information right now. However, this particular website's characterization of the weapon as a "machete" when many other sources have reported it more precisely as a "kukri knife", which I understand to likely be a significantly smaller and therefore less threatening implement, certainly calls into question this website's objectivity.

Edit: Also it seems that the blood was likely his own? No mention of him attacking anyone specific. So characterizing him as wielding a "bloody machete" -- implying he had assaulted people -- is also journalistically questionable.
