It was said he had received certain unrequested photos and he may have deleted them but they were still on his phone because we can never delete completely. It was said that he asked that no illegal photos be sent to him. I have no other comment to make on his other illegal dealings. However, people cannot control what has been sent to them and it is on your data even if deleted.
This has made me think back to the early 90s, the beginning of the web revolution for me, we were living in Beijing. Someone we barely knew from Germany sent my exh a photo of a scantily dressed woman, not even UK page 3 level, we deleted it. We thought it was weird to have been sent it but the imprint was on our computer even though it had been deleted.
