A BBC spokesperson said: "We treat any allegations very seriously and we have processes in place to proactively deal with them.
"As part of that, if we receive information that requires further investigation or examination we will take steps to do this. That includes actively attempting to speak to those who have contacted us in order to seek further detail and understanding of the situation.
"If we get no reply to our attempts or receive no further contact that can limit our ability to progress things but it does not mean our enquiries stop.
"If, at any point, new information comes to light or is provided - including via newspapers - this will be acted upon appropriately, in line with internal processes."
This seems to suggest that the complainant has not been forthcoming with information.
I would keep an open mind on this one for the moment.
Just because your teen tells you the money came from X doesn't make it always true.
