The 28-year-old rapper is set to appear in court to face a judge later on Friday, but is currently in jail in Van Nuys.
For Soulja, the arrest comes after he was previously taken into custody in 2016 when he was already on probation, and police searched his home after he threatened people online. During their search, police found at least one weapon, which was a violation of Soulja's probation.
At the time, a judge extended the 'Pretty Boy Swag' rapper's probation, and made it clear he wasn't to have guns or ammunition in his possession.
The 'Kiss Me Thru The Phone' singer was also previously charged for the illegal possession of a firearm in 2017 when he was found with a Mini Draco AR-15 - which is illegal to own in the US state of California - and he has also been charged for allegedly stealing a gun from a police car.
