HACKENSACK - The second man charged in a series of attacks on synagogues in Bergen County has pleaded not guilty.

Prosecutors say Aakash Dalal, 19, of New Brunswick, is charged with conspiracy, aggravated arson, bias intimidation and criminal mischief. He allegedly played a role in the January attacks, which included the firebombing of a house of worship where a rabbi and several family members were sleeping upstairs.

Dalal appeared in a Hackensack courtroom earlier this morning. His plea was entered by his attorney. He's being held on $2.5 million bail.

After Dalal was arrested Friday, Bergen County Prosecutor John Molinelli characterized him as an instigator in the firebombings allegedly carried out by then-19-year-old Anthony Graziano.

Dalal is alleged to have encouraged Graziano and showed him how to make the bombs.
