Police say four men accosted three teenagers at an east-side park on Saturday evening in Sioux Falls and forcibly took two cell phones.

Officer Sam Clemens says a 16-year-old male and two females, 16 and 19 years old, were in Harmodon Park around 6:30pm Saturday when four men drove up in a vehicle, got out and began punching the boy.

The men took the boy's phone and a phone from the 19-year-old, and then they left.

Clemens says the teens were unable to give police any description of the robbers, and police don't know if it was a random incident.
