Revoke all permissions from list item

Dec 8, 2011 at 4:09 PM

Is there a way to remove all permissions (SharePoint Groups) from a list item that are inherited from the parent list?  By default when a new list item is created it will inherit the permissions from the list. I need to remove all the inherreted permissions and then assign the required item level permission. As far as I can see, the Delete List Item Permission Assigment action requires as specific user or group to remove.
