Madonna's teenage son Rocco Ritchie has been arrested in a drugs bust.

Rocco was caught in possession of cannabis after neighbours reportedly called police on the troubled teen.

The 16-year-old, whose father is director Guy Ritchie, was seen 'smoking or doing drugs' near his Primrose Hill home in North London.

Sources told the Sun that Rocco was seen tossing something away as police approached him in Steeles Mews North, Camden.

When officers noticed traces of cannabis on his clothes they searched him and found a small quantity of the drug.

He was arrested on September 28, taken to a north London police station and later bailed.

A police spokesman said: 'A 16-year-old youth has been arrested for possession of cannabis.

'The arrest follows a stop and search by officers from Camden borough at around 5.15pm on Wednesday, September 28 at Steeles Mews North.

'The youth was taken to a north London police station. He was subsequently bailed and dealt with by Camden borough's Youth Offending Team.

'He was dealt with by way of Triage, which uses multiple strands to engage and educate young people in order to prevent re-offending.'

Earlier this year the teenage was at the centre of a bitter custody dispute between his director father and pop icon mother.

The disagreement began in December 2015 during a falling out between Rocco and his musician mother when he abandoned her Rebel Hearts tour.

He refused to travel with his mother and she launched legal action in the US and UK demanding custody of her son.

Guy Richie's lawyers argued Rocco was settled in school in London and, in September, he won the bitter nine month battle over where their son should live.

The Sherlock Holmes director reached a settlement with the pop star hours before they were due in court in New York and it was agreed the teenager would continue to live in London.

Website TMZ claimed that Madonna thought Guy 'had poisoned her son against her' and, 'as the disciplinarian [parent], she felt guy was way too permissive'.

The terms of the custody agreement remain confidential, but it is understood Rocco is schooled in London, with regular visits from his mother.
