DES MOINES, Iowa — Four teenagers have been charged as adults after police in Norwalk say they assaulted and robbed another teen during a drug deal.

The Norwalk Police Department said the incident took place on Saturday, May 24 and started with a Norwalk teen conversing with someone over social media about a drug transaction. A plan to meet in the 900 block of East 17th Street in Indianola was set. Court documents filed in the case say the deal was to buy marijuana and a THC cartridge for $50.

Police said that when the victim showed up to complete the transaction, he was assaulted by four teens. They allegedly threatened to shoot him and stole his cell phone, an iPhone 14+.

NPD said witnesses broke up the altercation, and police were called. The West Des Moines Police Department and the Warren County Sheriff’s Office assisted NPD in locating three suspects who were arrested and charged with first-degree robbery, among other offenses. The fourth suspect in the robbery was identified later and arrested.

One of the teens had two handguns on him during the incident. The weapons were seized.

A preliminary hearing for the teens is scheduled for June 2nd.
