Neiman Marcus invests in more security after man brings gun into store

CHICAGO - Neiman Marcus is investing in more security after a customer brought a gun into the Michigan Avenue store this week. 

In a statement, the company says, "To reinforce our commitment, we are investing in additional security measures in select stores. In addition to Neiman's full-time, in-store security team, we are now working with a private security form and its k-9 unit for weapons detection."

On Monday, Neiman Marcus on Michigan Avenue said a gun-sniffing dog alerted his handler of a potential weapon.

Security monitored that person on surveillance video, and watched as he stuffed multiple items into his pockets.
