Clayton, N.C. — Police arrested a second man for allegedly aiding in baseball attack on a Wal-Mart employee and filed more charges against the original suspect.

Lt. J.R. Herring arrested Brandon Michael Nicopolis, 21, of 321 Tobacco Lane in Johnston County, at his home without incident on Friday.

Investigators said that Nicopolis drove around Thomas Michael Accardi, 21, of 2008 Huntclub Drive in Johnston County, on the night of Aug. 7, when Accardi attacked Arnold Dyer in the parking lot of the Wal-Mart at 805 Town Center Blvd.

Investigators filed six additional charges of misdemeanor injury to personal property against Accardi. He also faces charges of malicious assault in secret and assault with a deadly weapon with intent to kill inflicting serious injury.

A judge raised Accardi's bond to $400,000 at his first court appearance on Monday, and he was still being held in the Johnston County Jail on Friday.

Accardi was released from prison in April 2007 after serving eight months for common-law robbery, according to state Department of Correction records.
