Bruno Mars fans come to rescue over ticket scam

A young Bruno Mars fan was left in tears after finding out his tickets were fake - only to have his night rescued by two fellow fans.

Carmen Bird was on her way to last night's Auckland show by the chart-topping pop star when she saw a young fan crying with his mum.

"We went over to him and said, 'What's going on?'" Bird, who was with her friend Alison, told Sarah, Sam and Toni on The Hits this morning.

The Christchurch mum and her son had arrived at Spark Arena expecting to see Bruno Mars at the second of his four-night Auckland stand.

They were clutching tickets given to them by the child's grandmother for Christmas.

But there was a problem.

"His nana had bought their tickets for Christmas for $700 on Viagogo ... the tickets had been cancelled," said Bird.

Viagogo is a controversial ticket resale site that offers tickets to popular shows at sometimes inflated prices.

Fans have complained that they don't get the tickets they paid for, or arrive at the venue to find that the tickets have been cancelled.

Standing in front of the venue just moments before the show was due to start, Bird initially took to Facebook asking for anyone with spare tickets if they could help the mother, 24, and her son, 9, out.
