Some nut with a hatchet attacked and injured two police officers in New York City today.

CNN correspondent Jim Sciutto reported Thursday that investigators suspected a link to radical Islam and police were specifically looking into posts Thompson made on social media.

Additionally, Buzzfeed notes that a "Facebook page matching Thompson's name and location showed a photo of a masked fighter, as well as a banner with Arabic writing." However, nothing has been confirmed yet.

About a month ago, ISIS called for lone-wolf attacks against the US and its allies.
