Several outlets reported early Sunday morning that officials found a pressure cooker device just four blocks away from the site of the first explosion. The device was connected to a cell phone and wires.

An unconfirmed picture emerged on Twitter Moments as part of the official story.

New York City Mayor Bill DeBlasio called the initial bombing “an intentional act,” but has no yet placed terrorism as the cause.

29 people were injured in the attack. Officials are asking that any tips be sent to 1-800-577-TIPS, according to USA Today.
