Nomads bikie arrested at Castle Hill over murder threats A member of the Nomads outlaw motorcycle gang has been arrested by Gangs Squad detectives at Castle Hill after allegedly threatening the safety of a number of people. Police allege the man made a number of threats over the phone to a business operator and his family, as well as other staff members, after a business deal soured. One of those allegedly threatened has since fled overseas with his family due to fears for his and his family's safety. At 9am yesterday, a 44-year-old man was arrested when he attended Castle Hill Police Station. He was charged with six counts of using a carriage service to threaten to kill, and three counts of using a carriage service to threaten serious harm. He was granted conditional bail to appear in Parramatta Court on Wednesday, April 17.
