Just two days following the dramatic explosion in the Chelsea district of Manhattan, a main suspect was arrested this morning by FBI and several other law enforcment agencies.

After a day long manhunt, authorities apprehended 28-year-old Ahmad Khan Rahami in an armed standoff that ended with Rahami and at least one officer wounded.

Authorities are looking at possible links between the Chelsea blast and a pipe bomb that was found in New Jersey Saturday morning, as well as five suspicious devices found near a train station on Sunday night. Reports are growing that a terror cell may very well be behind the attacks.

On Sunday night, federal authorities arrested five suspects in the Chelsea district bombing, which injured 29 people.

Police also responded to reports of a backpack with suspicious wires and a pipe found amongst garbage near a New Jersey train station.

One of five devices in the backpack exploded as the FBI attempted to disarm it with a robot. It was the third attack in 24 hours.

Police have not said whether they believe the backpack is linked to the bombs in Manhattan, or an earlier pipe bomb at a train station in Elizabeth, New Jersey, but law enforcement officials said on Monday that they were investigating a possible terror cell operating between New York and New Jersey.
