The F.B.I. arrests a man who had carried zip ties into the Capitol.

The F.B.I. arrested a man on Sunday who was photographed in the Senate chamber clad in military-style clothing and holding zip ties after internet researchers managed to piece together his identity.

Law enforcement officials said the man, Eric Gavelek Munchel, 30, was taken into custody in Nashville on federal charges. One of the officials said the authorities had recovered several weapons. No further details were available. Charges were expected to be announced soon.

Efforts to reach Mr. Munchel before his arrest were unsuccessful. He is one of more than a dozen people charged by federal authorities in connection with the attack on the Capitol.
