Police officer's son pleads guilty to terrorist bomb plot

A Boston police captain's son has pleaded guilty to plotting a terrorist attack on a college campus to support the Islamic State group.

Alexander Ciccolo pleaded guilty in Springfield's federal court Monday to attempting to provide material support to a foreign terrorist organization and attempting to use weapons of mass destruction, among other offenses.

The plea deal calls for a 20-year prison sentence.

Ciccolo was arrested in July 2015 after receiving guns from a federal informant. Prosecutors say he told a cooperating witness that he wanted to attack a university using guns and homemade bombs similar to the pressure cooker bombs used in the 2013 Boston Marathon attack.
