Spying allegations and more tour-ending injuries marred a gutsy win for the British and Irish Lions in Brisbane on Saturday.

Lions coach Warren Gatland said two members of his staff were forced to chase away an unidentified person found filming a training session at NIB Stadium in Perth this week.

It is understood the strength and conditioning trainers insisted the person delete the footage they had recorded.

Gatland also said the Lions had seen Wallabies staff filming the team's game against the Force on Wednesday, which is not forbidden practice.
