The Sunderland winger is accused of two counts of sexual activity with a girl under 16. Jurors will begin to hear his case tomorrow morning at Bradford Crown Court.
The force has reiterated that anyone who identifies someone who may or may not be a victim of a sexual offence is committing a criminal act.
Durham Constabulary is urging social media users to take care with what they post - and reminding people that anyone who breaks the law will be dealt with robustly.
Johnson, 28, yesterday admitted one count of meeting a girl under 16 following sexual grooming, and one count of sexual activity with a child.
He has denied two further offences of sexual activity with a child, and will stand trial on these charges. A jury has been sworn in, and will return to court at 10.30am tomorrow.
