Amy Winehouse died after drugs including cocaine, ecstasy and ketamine, it has been claimed, after sources said they saw her buying drugs hours before her death. However, other reports suggest that the singer may have died following a drinking binge.

Police have not yet confirmed the exact cause of Winehouse’s death, but claims have emerged that she bought drugs from a dealer in Camden at 10:30pm on Friday.

Another source from a Camden pub told The Sun that Amy was seen buying cocaine from a well-known dealer in the area.

Meanwhile, friends of the star told the Sunday Mirror that they believe she died from a “bad” ecstasy pill mixed with a large amount of alcohol.

Winehouse also suffered from emphysema, which is a disease of the lungs that causes shortness of breath.

A friend told the newspaper: “It was an ecstasy overdose. She could do cocaine until the cows come home. But this was obviously a dodgy pill.”

However, despite claims that Winehouse bought drugs the night before her death, according to the preliminary police investigation no drug paraphernalia was found at het home.

Police sources are suggesting that she died following a drink binge.

Winehouse's PR spokesperson Chris Goodman told The Sun: “Amy was on her own at home apart from a security guard who we had appointed to help look after her over the past couple of years.

“She was in her bedroom after saying she wanted to sleep and when he went to wake her he found she wasn't breathing.

“He called the emergency services straight away. He was very shocked. At this stage no-one knows how she died. She died alone in bed.”

Winehouse’s family will be given the results of her post-mortem examination today and will then be allowed to bury her.
