The FBI made an arrest Saturday connected to the mass shooting that shocked Jersey City this week.

Newser reports New Jersey pawnshop owner Ahmed A-Hady was arrested Saturday.

Authorities found six rifles, including three AR-15-style assault rifles, three handguns, and one shotgun in A-Hady's shop.

They also found 400 rounds of ammo including hollow-point bullets at his home.

Federal prosecutors say the 35-year-old "falsely denied" keeping two handguns in the store.

However, a relative of his later told authorities he had a safe at the store with guns stashed inside.
