LONDON — model Kate Moss apologized Thursday to "all the people I have let down'' after allegations that she took cocaine - but stopped short of explicitly acknowledging that she had used the drug.

In a statement, Moss said: "I take full responsibility for my actions. I also accept that there are various personal issues that I need to address and have started taking the difficult, yet necessary, steps to resolve them.''

"I want to apologize to all of the people I have let down because of my behaviour, which has reflected badly on my family, friends, co-workers, business associates and others,'' the statement said. "I am trying to be positive, and the support and love I have received are invaluable.''

The waif-like model's problems have multiplied since the Daily Mirror newspaper last week published photos that appeared to show her snorting cocaine. She has been dropped from campaigns by H&M and Burberry, and Chanel said it was not renewing her contract.

London's Metropolitan Police said it is investigating the newspaper's claims of drug use.
