Captain Jim Hoekman of the Minnehaha County Sheriff's Office says authorities surrounded a house in Dell Rapids early Friday morning following a threatening phone call to 911.

"Male person called 911 stating he was going to kill his daughter and would kill anyone that would approach the house. The caller also said he would kill himself. When deputies arrived they set up a perimeter. They handled the call as if it was a barricaded subject. Through the course of the investigation, we found this was indeed a false report."

Hoekman says investigators are in the process of finding the caller.

"Currently, detectives are aggressively following up on leads. They are also working with the phone company and tracing the phone number. I am asking the public this---if anybody out there with information following this case, please contact Crimestoppers at 605-367-7007."

Hoekman says he isn't aware of previous fake calls in Minnehaha County.
