The 38 year-old admitted to trading insults with a South African passenger after Riley told the man to keep quiet. 'We didn't see eye to eye,' Riley said.
Australian Protective Services met Riley at the airport in Perth and accompanied him to collect his bags and took him to a waiting car. Riley said he suspected APS was present only to ensure the argument did not resume at the Perth terminal.
No charges have been filed.
