I should say “wanna be Batman”, as I have a feeling it wasn’t Bruce Wayne. Police in Washington were called out to a bar regarding a man assaulting the bouncers with a knife affixed to a pole. After threatening an employee with his spear, the man fled with officers in pursuit. He threw something at the vehicle, and officers later discovered it was a Batarang: a sharpened ninja star in the shape of a bat. This Batman didn’t get away, and was arrested for felonious assault, and more charges expected.

We’ve covered some superhero arrests on Crimcourts before, and in researching this, I discovered that there had been some Batman arrests that I had missed. None of them involved a Batarang, however.
