ROME, Wednesday 11 August 2010 (AFP) - Police raiding a drug den in the Italian capital were confronted by an aggressive albino python used to intimidate addicts, police said Wednesday.

Police had been tipped off that they would find "an animal" during the raid on the apartment in the centre of Rome, and when they opened the door they saw a striped yellow and white snake curled up on a heat mat.

The snake, which was 3 metres (10 foot) long and was kept hungry so that it would be more aggressive, was allowed to roam the apartment to scare addicts into paying for their drugs, police said.

Animal services were called to capture the snake, which was tempted into captivity using a whole chicken and sent to nearby zoo.

The reptile had been resting on 200 grammes (7 ounces) of pure cocaine, and a further five kilogrammes were found in the apartment.

Six people were arrested in the raid, on top of another six who were already in custody.

The 12 were charged with conspiracy to traffic cocaine and illegal possession of a protected species.
