London, July 27 : The police are still looking for the drug dealer who sold the heroin to Peaches Geldolf that killed her.

According to sources, the astonishingly high purity levels of the drug mean that somebody is selling heroin at a strength that is well capable of killing again, the Mirror reported.

Cops have identified a "handful" of suspects who they believe could have sold her the lethal batch and have also narrowed down the search for a possible "pick-up" spot to several key areas visited by Peaches in the days before she died - including central London.

They had found 6.91g of the drug in a bag at the 25-year-old model's home with a purity of 61 per cent, more than twice that of street-level heroin and worth up to 550 pounds.

Peaches died in April with 3mg of heroin per litre of blood in her system, which was ten times the level that killed her mother Paula Yates in 2000. (ANI)
