The new bill, if you have read it, has only four provisions, and only one of them deals with citizen's arrest. Clause 3 of the new bill amends the existing right for someone in lawful possession of property to arrest anyone found committing an offence in relation to that property; it amends it by allowing one to arrest a person who they have previously found committing an offence in relation to their property, but only where it's not feasible for an officer to make that arrest.
Are you familiar with that part of our new bill here?
