Rapper 2 Chainz was arrested in NYC’s LaGuardia airport earlier today (May 22, 2012).

The Atlanta rapper formerly known as Tity Boi was popped for allegedly carrying a weapon.

But you’ll never believe what the “weapon” was!

Details…

According to TMZ, 2 Chains was popped for transporting the 4 finger ring pictured in the lead photo. The same one he rocked this weekend during Drake’s concert!

2Chainz wasn’t packing brass knuckles when he was arrested today in New York … it was just a harmless 4-finger ring — this according to sources close to the hip hop star.

The ring says “DOPE” in big letters — and sources tell TMZ, 2 Chainz rocked it no problem at an Atlanta club called the Velvet Room on Sunday.

According to sources close to the rapper, Chainz then flew to NYC without incident — with the ring in his luggage — but when he tried to leave the city today, TSA at LaGuardia Airport mistook the jewelry for a dangerous weapon.

2 Chainz was arrested at the airport for possession of a criminal weapon around 1:45pm this afternoon when officials found the 4-finger ring in his bag.

The rapper is currently still in custody as the NYC Port Authority PD works this all out.

Somebody get Diddy on line one…

*UPDATE* 2 Chainz is out and recently boarded a private jet to his next destination…
