A high risk traffic stop that prompted authorities to shut down part of I-43 Wednesday morning resulted in no arrests, according to a news release from the Milwaukee County Sheriff's Office.

An hour-long search for a weapon also turned up nothing, according to the news release.

Starting around 11 a.m. authorities diverted traffic off the Southbound lanes of I-43 starting at Brown Deer Road. Traffic was able to re-enter the interstate at the Good Hope Road exit.

The reason for the traffic stop or why it was considered 'high risk' has not been discussed. The subject of the traffic stop was released after questioning.

During that traffic stop several witnesses called to report someone had picked up a gun off the freeway nearby. Police investigated and learned that the item was actually a handheld radio, according to a press release.
