Why did the friend go to the police to start with?
It appears to me that the friend has no interest in this and is sticking her nose in where she shouldn't. No crime has been committed, the police will have seen that having interviewed your friend and I would forget about this and enjoy your friend's generosity to you. I hope that help. Please leave a positive rating so that I am credited for my time.
Presumably he doesn't. That is a stupid question for the police to ask and why they are taking any further interest in this really is strange. There is no crime here.
Thank you. I will look out for it.
