KEY POINTS:
Pete Doherty has apologised for returning to drugs, saying it was a "stupid, stupid action for which I feel only shame".
The Babyshambles frontman was captured on video injecting himself with heroin just hours after claiming he was drug-free.
Yesterday Doherty's record company issued a statement saying the singer was "looking to check himself back" into rehab.
The EMI statement said: "Peter Doherty would like to apologise to the medical staff, fans and well-wishers who have helped and encouraged his progress in fighting his addiction to heroin."
