(CNN) A handwritten note in a killer's back pocket helped lead to the arrest of a man connected to a gunman in last week's Jersey City mass shooting, authorities said. Ahmed A-Hady of Keyport, New Jersey, was arrested by FBI agents Saturday. The 35-year-old faces a charge of being a previously convicted felon in possession of a firearm, the US Attorney's Office in New Jersey said. Investigators say A-Hady's phone number was found on a handwritten note in the back pocket of David N. Anderson, one of two assailants who gunned down a Jersey City police officer and then killed three people at the Jersey City Kosher Supermarket. The note in Anderson's pocket "contained a telephone number ending in 4115, and a Keyport, New Jersey, address," the US Attorney's Office said.
