Police are searching for a “person of interest” in the chaotic attack on a Brooklyn subway during rush hour Tuesday morning, a man they say posted violent ramblings online.

But authorities stopped short of saying the man they identified, Frank James, 62, was considered a suspect. Police said he was not in custody as of Tuesday night and no charges were filed.

No one died but the attack left at least 29 injured, New York Police Commissioner Keechant Sewell said at an evening news conference. James has ties to both Wisconsin and Philadelphia, authorities said.
