Edward Mathews, seen in his mugshot from the Burlington County Prosecutor's Office, is facing new charges following his arrest in July.

(CNN)A New Jersey man arrested in July after a video showed him shouting racial slurs at a neighbor has been charged "with leaving a threatening note on one of his victim's cars earlier this year," as well as vandalizing the victim's vehicle, according to a news release from the Burlington County Prosecutor's Office.

Edward Cagney Mathews, 45, was served with charges of bias intimidation in the fourth degree and harassment at Burlington County Jail, where he's been since his July 5 arrest, according to the news release.

This most recent charge against Mathews was filed after the FBI performed a handwriting analysis on the note left on a neighbor's vehicle in January, the prosecutor's office said. The analysis revealed Mathews wrote the note and had smeared feces on the vehicle, it said. CNN has not been able to reach Mathews' attorney.

n investigation following Mathews' July arrest by the Burlington County Prosecutor's Office and the Mount Laurel Police Department has resulted in 22 charges against him since July 2, including bias intimidation, harassment, criminal mischief, possession of a weapon for an unlawful purpose and stalking, according to the prosecutor's office. The charges are pending presentation to a grand jury for possible indictment, the office said in the news release.

The prosecutor's office released the results in a 25-page report Tuesday. Read the full article on CNN.
