A police report on the arrest states that Gray "fled unprovoked" and that an illegal switchblade knife was later found on him.
Gray was charged with carrying an illegal knife, but authorities have come to differing conclusions about it. Baltimore State's Attorney Marilyn J. Mosby said in announcing charges against six officers that the knife was not an illegal switchblade under Maryland law. Baltimore police have said the knife violates city code.
A defense attorney for one of the officers has challenged the claim by prosecutors that Gray was falsely arrested and filed a motion demanding to inspect the knife.
