Transcript for Brussels May Not Have Been Terror Group's First Choice for Attack
And overseas to the terror investigation in Brussels. A stunning new revelation after the arrests of several suspects.

Reporter: New troubling revelations tonight from the man in the hat, Mohamed abrini. He told interrogators that the deadly attacks in Brussels were not the original plan.

Authorities say abrini has admitted that after the two suicide bombers detonated themselves at the airport, he fled, the escape recorded by surveillance cameras. On the way, he claims he ditched his tan coat in the garbage, and sold the hat. Anytime you arrest key players in a network it gives you the opportunity to figure out the network. Reporter: Abrini has now been charged with terrorist murder, along with Osama krayem, a 23-year-old Swedish national.
