(CNN) -- An eight-year-old girl was ejected from a junior tennis tournament in New Zealand when officials discovered she was wearing a hidden radio earpiece to receive instructions from her father.
According to the Associated Press, tournament referee Rob Wilkinson said officials became suspicious of the "heightened number of questioned calls" coming from Ukrainian-born Anastasiya Korzh.
After closer inspection officials found the earpiece hidden under the girl's headband, linked by a cord to a receiver under her shirt.
The Press Association of New Zealand reported that Korzh's father claimed only to be helping his daughter keep score in the under-10 tournament in Christchurch.
The girl was playing in her first tournament.
