Establishes third degree crime of gang assault.

S 1020 creates a new third-degree crime in New Jersey for "gang assault," defined as causing bodily injury to another person when aided by two or more other people actually present and with intent to cause harm. It directly affects individuals who commit violent assaults in groups of three or more, including those targeting third parties. The bill specifies that "bodily injury" includes physical pain, illness, or physical impairment, and sets penalties of 3-5 years in prison, a $15,000 fine, or both. This law is modeled after a similar provision in New York state law.
