A 35-year-old man from Golden Grove was charged as a participant in a criminal organisation being knowingly present in public place with two or more other participants.
All three have been bailed to appear in the Adelaide Magistrates Court on 7 March.

The laws are in place to protect the community from people who have no regard for public safety and whose behaviour is unacceptable to the wider community.
