A tennis body has apologised for not protecting children after a Wrexham coach sexually abused a girl.
Daniel Sanders, a former professional player, was jailed for six years in July after admitting eight counts of sexual activity with a child.
The Lawn Tennis Association (LTA), the sport's governing body in the UK, said the actions they had taken to protect children were "not enough".
A spokesman said an independent inquiry was taking place into what happened.
Sanders, originally from Wrexham, once played doubles with Tim Henman and played his last professional match in 1996.
