Record company reps for Pete Doherty sent PEOPLE an apologetic statement Wednesday in an attempt to shame the Babyshambles singer into sobriety. It was just Tuesday that the troubled star spoke out about missing drugs
– and photos surfaced of him allegedly using heroin again.
The letter reads:
"Peter Doherty would like to apologize to the medical staff, fans and well-wishers who have helped and encouraged his progress in fighting his addiction to heroin. His ongoing rehabilitation was a source of such pride to him that Peter and those closest to him thought that he was close to winning his personal battle with the drug. However, Peter sadly relapsed last week and is now looking to check himself back into a rehab clinic so that he can try to continue the hitherto excellent attempts he had made to break free of heroin. He realizes that he has not only let himself down but has let down those who trusted and encouraged his efforts and he is filled with remorse for what he describes today as, 'a stupid, stupid action for which I feel only shame.'"
