(CNN) Four people with alleged ties to a neo-Nazi group known as Atomwaffen Division have been arrested after authorities said they conspired to harass journalists and people affiliated with the Anti-Defamation League.

The group focused on targets who were Jewish or people of color, according to the US Attorney's Office for the Western District of Washington, and sent them threatening posters to intimidate them.

The arrests came the same day a fifth individual -- said to be Atomwaffen Division's former leader -- was arrested in Virginia for allegedly harassing a member of President Trump's Cabinet, journalists and a university.

According to the office of US Attorney Brian T. Moran, 24-year-old Cameron Brandon Shea of Redmond, Washington; 24-year-old Kaleb Cole of Montgomery, Texas; 20-year-old Taylor Ashley Parker-Dipeppe of Spring Hill, Florida; and 20-year-old Johnny Roman Garza of Queen Creek, Arizona, face charges of conspiracy to mail threatening communications and commit cyberstalking.

An attorney for Shea has not responded to a request for comment. CNN has been unable to determine whether the other defendants had attorneys who would comment on their behalf.
