According to this article (ABC News):
http://abcnews.go.com/blogs/headlines/2013/04/live-updates-boston-bombing-suspect-dead-in-shootout/
7:53 p.m. ET: Three college-aged individuals were taken into custody by the FBI late this afternoon in connection with the manhunt for bombing suspect Dzhokhar Tsarnaev, Lt. Robert Richard of the New Bedford Police Department told ABC News. The three people were taken in for questioning, he said.

I just posted another thread with a Daily Mail article that I believe goes into this in some more detail:
