Wiz Khalifa was arrested for weed possession over the weekend, but he made sure to make the most of his experience, turning his arrest into promo for his new mixtape, 28 Grams.

The rapper tweeted out some hilarious photos from inside his cell, promising the release of his mixtape as soon as he was free.

Khalifa delivered on the promise, but El Paso cops still have some questions-- namely 'how was the rapper taking and tweeting out photos while incarcerated'?

It goes without saying that those taken into custody are not allowed to bring their phones with them, so police are looking into whether Wiz was left unsupervised, or was perhaps even assisted by a jailer.

More info to come as it arrives. Grab Kahlifa's 28 Grams mixtape here.
