Image shows IED that was placed in French Quarter by New Orleans truck attacker, officials say

A photo showing what a law enforcement official said is one of two improvised explosive devices that investigators believe were placed in the French Quarter by the man responsible for the deadly New Orleans truck attack on New Year's Day was obtained by CBS News Tuesday.  

The photo, which was provided by a senior law enforcement source with knowledge of the situation, shows rolls of nails and what appears to be a radio receiver inside a cooler.

The photo of the IED was first published by ABC News.
