New York police have released a photo of Ahmad Khan Rahami, 28, a suspect in the bomb attack on New York.
New York officials have identified a suspect wanted for questioning over Saturday's blast in the Chelsea area of the city.
The man has been identified as Ahmad Khan Rahami, 28, a naturalised US citizen from Afghanistan.
The New York Police Department (NYPD) has released a photograph.
The explosion injured 29 people. Both the detonated bomb, and a device found nearby, were shrapnel-filled pressure cookers, according to US media.
Investigators have warned the suspect, whose last known address was in Elizabeth, New Jersey, should be considered "armed and dangerous".

One of the devices exploded early on Monday when a bomb disposal robot tried to deactivate it.
