By all accounts he volunteered himself at a Police station at 0530am yesterday morning to be interviewed in connection with the incident.
Neither the BBC nor any other agency will comment or speculate. The matter is now in the hands of the Police to investigate further, carry out more interviews and establish if there is any case to bear. And this is why the BBC will not comment further on the subject, there is no statement to be made and certainly no "explanation" due to Joe Public.
Ricky will perform on Saturday night, anything about the alleged incident with the photographer is just that, an alleged incident until the Police state otherwise, or announce there is case to answer.
