Police officers were reportedly called to the Crank That (Soulja Boy) star's home in the Hollywood Hills after he allegedly posted threatening messages on his social media sites.

According to TMZ, cops found a gun at the 26-year-old's pad and arrested him.

The arrest comes two months after he was sued for posting a threatening video on Instagram, in which he blasted his ex-girlfriend Nia Riley and vowed to shoot and kill a man he believed was her new lover, while waving a gun at the camera.

His representative subsequently played down the threatening footage, insisting the firearm was a fake, and claimed he had also apologised to Riley.

The plaintiff, going by the name Skrill Dilly, claimed he suffered medical issues as a result of the stress and fear he lived in following Soulja's post, and sued for damages and funds to cover his medical expenses.

Soulja Boy is currently on probation after he pleaded no contest to a misdemeanour charge of unlawfully carrying a loaded firearm in 2014.
