A 20-year-old man from Los Angeles has been arrested after promising to shoot someone if his post was retweeted 100 times on Twitter.

Dakkari Dijon McAnuff uploaded a picture to the micro-blogging service showing a rifle pointing down a street from the top of a building. The caption read “100 RT's and I shoot someone walking,” according to reports from the LA Times.

A subsequent tweet included a picture appearing to show a wounded man with the caption from McAnuff’s Twitter account (now suspended) reading “Man Down. Mission Completed.”

Police were alerted to the pictures and quickly tracked McAnuff to his home on the 700 block of West Ninth Street in downtown LA. McAnuff was arrested on suspicion of making criminal threats with a bail set at $50,000.

Thankfully, the police later determined that the pictures were posted as a joke, with McAnuff’s gun revealed to be a relatively harmless airsoft rifle.

The picture contained in the original tweet was reposted by local news editor Julie Sone, although social media accounts associated with McAnuff shows him posing with what appears to be as similar rifle.
