DES MOINES, Iowa (AP) — Authorities say a Missouri man was beaten and robbed near the Iowa State Capitol after leaving a popular annual music festival.

The Des Moines Register reports that the attack happened around 11:30 p.m. Friday as the Lee’s Summit, Mo., man left the 80/35 music festival.

The man told police he was in Des Moines for work and went to the festival on Friday night. He says he met some females at one of the concerts who claimed to know about an after-party they should all attend.

Police say the group met with three men after the concert. The females left the group, and the man says he was then attacked. He says his assailants took roughly $1,000 from his pockets and his phone.
