Ahmad Khan Rahami, the man identified as the New York bombings suspect, is in custody after apparently being injured in a shootout with police in Linden, New Jersey.
Footage showed Ahmad Khan Rahami apparently conscious on a stretcher. Two police officers were injured in the exchange.
Linden is four miles south-west of Elizabeth, New Jersey, where further devices were found late on September 18.
Ahmad Khan Rahami, a 28-year-old Afghan-born US citizen, had been named by the FBI as a suspect in September 17 bombing in Manhattan.
His family home in Elizabeth was being searched by officers.
The bombing in the Chelsea district of Manhattan injured 29 people. An unexploded device was found nearby.
On September 17 a pipe bomb exploded in a New Jersey shore town ahead of a charity race. No-one was hurt.
President Barack Obama said officials did not believe there was a connection between events in New York and New Jersey and the stabbing attack in Minnesota, also on September 17, in which nine people were injured.
