NEW YORK - The man accused of setting off the bomb in Chelsea pleaded not guilty to eight federal charges Thursday during an arraignment in Lower Manhattan.

Ahmad Rahimi was indicted Wednesday on charges that include using a weapon of mass destruction and bombing a place of public use.

He is accused of setting off a bomb on West 23rd Street in September that left more than 30 people hurt.

Investigators also believe he set off a pipe bomb just before a 5K run in a New Jersey town earlier that day.

Rahimi was injured days later in a gunfight with police in Linden, New Jersey.

Last month, he pleaded not guilty to the charges of attempted murder related to that shootout.
