A showjumper threw away his mobile phone and burned his mattress just days before being arrested over having a threesome with an underage girl and a horse rider, a court was told.
Horse-riding instructor Guy Simmonds, 37, and fellow rider Lauren Jarvis, 26, allegedly had sex with the schoolgirl in January last year despite knowing she was under 16.
Simmonds, who ran a riding school in the Monmouthshire village of Undy, is accused of six counts of engaging in sexual activity with a child.
His co-defendant Jarvis, from Newport, faces one count of the same offence. Both have denied all charges against them.
The jury at Cardiff Crown Court was this week played a police interview in which Simmonds claimed he threw his phone away at a Tesco supermarket because it was broken.
