He was jailed for two years for aggravated identity theft.
The rapper was accused of stealing bank card numbers and identifying information of their owners. He allegedly stole $15,388 from the unsuspecting victims.
Before he went to prison, Sinzu's music career had taken a nosedive but he was struggling to revive it.
His jail term, however, shattered whatever that was left of the sloppy career.
On Sunday, March 25, 2018, a video surfaced on Instagram, captioned "My bro is back!! SINZU".

In the video, the rapper, clad in a black T-shirt, durag, and a red pant was seen being welcomed home.
Falemi came on the Nigerian music scene in 2005, with an impressive jam, his first ever single 'Omoge' featuring the legendary Mike Okri.
In 2006, he dropped his first mixtape 'Best of Both Worlds: Money Long The Mixtape', which cemented him a spot in the Nigerian music industry.
The mixtape is still regarded as one of the best.
