A caller to a Sydney radio station on Monday alerted the NRL to the latest claims from Brookvale Oval, where Manly forward George Rose was also hit in the back with a can while Bulldogs officials and staff manning a Canterbury merchandising van were abused.

‘‘We were sitting next to where the players’ partners and family members were sitting and a couple of Manly supporters were pretty much going off at one of the ladies there,’’ the caller, who referred to himself as Superfly, told Sky Sports Radio.

‘‘I didn’t know who she was and I pretty much told them to pull their heads in. They were pretty much racially vilifying her. The behaviour from these guys was absolutely disgraceful ... telling her to ‘go back where you came from’, one of them called her a ‘monkey’ as well.’’

McGuirk said the contents of the phone call had been passed on to Rugby League Central. ‘‘Our integrity department is aware of that one as well,’’ he said. ‘‘That is part of their investigation into that issue as well. Obviously speaking to the Bulldogs will be part of that process.’’

NRL officials met their counterparts at Manly on Monday about the events of last Friday night. They are confident that they can at least single out who spat at Barba and Halatau as they exited via the players’ race.
