Troubled rocker Pete Doherty has reportedly been arrested on suspicion of possessing heroin.

The Babyshambles frontman was pulled over by police after he was spotted driving erratically in East London.

Despite passing a breathalyser test, officers searching the 26-year-old arrested him after allegedly finding a supply of the illegal drug.

Doherty, who has been struggling with his addiction since splitting from supermodel girlfriend Kate Moss last month (NOV05), was bailed and will return for further questioning in the New Year (06).

The police incident adds to the singer's January court appearances, after also being arrested in November (05) on suspicion of possessing crack cocaine.
