The unprovoked assault was provoked by an uncontrollable rage from who is assumed to be Bruce Banner’s cousin, Jennifer Walters. The police and S.H.I.E.L.D. are on the look out. Banner has went into hiding yet again.
This makes the second crime committed by an Avenger; the first being Spider-Man robbing a guy. Hopefully Thor doesn’t snap too and cuts someone with a broken mug.
