It was drugs.
RadarOnline.com was the first to report that Sean Penn‘s 16-year old son was arrested at school last week, and now, we can reveal why.
Two sources familiar with the situation exclusively tells RadarOnline.com that the teen was arrested for having narcotics in his possession.
As we first reported Tuesday, the younger Penn was busted at the school he attends in the posh Malibu area.
At this time, authorities are not revealing what kind of drugs Penn had in his possession.
The drug arrest is sure to be fodder for Sean Penn’s adversaries, especially those who are outraged by his politics, and his meeting with Hugo Chavez.
The Venezuelan president has previously attacked America, saying drug consumption by U.S. citizens has led to problems in his country, as the two nations battled over the drug war.
The arrest of Penn’s son comes at a difficult time for the family. Just this past August, his mother Robin Wright Penn filed for divorce , declaring this time (unlike previous times when she withdrew divorce papers) that she has no plans to reconcile with Sean.
