"He [Rahami] appears to be in custody. They have apprehended him," Armstead stated in an interview with WABC-TV. "He has been injured. They shot him."
Ahmad Rahami is in custody after shooting a police officer in the city of Liden, New Jersey, NBC News reported citing sources.
The New Jersey mayor has later confirmed the information.
Earlier in the day, NYPD announced that it seeks 28-year-old Ahmad Khan Rahami in connection to the pressure-cooker bomb.
The 28-year-old and his relatives appeared to have filed a lawsuit against police officers in Elizabeth, New Jersey in 2011 which said they were subjected to "selective enforcement" on the grounds of their religion, The Daily Mail reported.
According to the lawsuit, filed in the federal court in Newark, the Rahimi family, US citizens of Afghan descent, have owned the chicken restaurant since 2002, and from the period between 2009 and 2011 were regularly targeted by police officers for staying open after 10 p.m, regardless of the authorization to do so.
Five people were said to be detained earlier in connection with the incident that officials previously declined to link to terrorism.
On Saturday, a total of 29 people have been injured in the explosion that hit New York City’s Chelsea neighborhood in Manhattan on Saturday night. Investigators found a second device that appeared to be a pressure cooker attached to wiring and a cellphone wrapped in a plastic bag on West 27th Street.
A bomb exploded near a US Marine Corps charity race in Seaside Park, New Jersey, about 82 miles south of New York City on Saturday morning. No one was hurt in the incident. On Monday morning, a third bomb exploded near a train station in Elizabeth, New Jersey as police explosives experts were trying to disarm the device.
