COSTELLO: In a matter of minutes we're going to be getting an update on capture of Paris terrorist attack suspect, Salah Abdeslam. Here's new video of his arrest.</s>COSTELLO (voice-over): Officials say he may have been plotting another attack after finding a large stash of weapons. Authorities now believe a large terror network kept him hidden for four months since those Paris attacks went down.</s>COSTELLO (on camera): Our senior international correspondent, Nima Elbagir, joins us live from Brussels, Belgium with more. Hi, Nima.</s>NIMA ELBAGIR, CNN SENIOR INTERNATIONAL CORRESPONDENT: Hi, Carol. Well, authorities have discovered that not only was he able to evade their capture for months, but he appears to have been able to recalibrate with an entirely new network. The cache of weapons, new associates, and new target right here in Belgium. That's in addition to their discovery that the network supporting the Paris attack conspiracy is much bigger than even they first suspected. Initially they say they were looking for about ten men. Already, Carol, they say they have about 30 arrested in custody and that search continues. One man who was only known to them previously by his alias, Sophian Kael (ph), believed to be a key conspirator. Counter terror officials tell us that intercepted phone calls between him and the Paris attack ring leader, Abaaoud, lead them to believe that he was in fact senior to Abaaoud. We're expecting more detail though, Carol, in that press conference in the coming moments.</s>COSTELLO: All right, Nima Elbagi reporting live from Brussels, Belgium, this morning. Thank you. The next hour of CNN NEWSROOM after a break.
