ELIZABETH, N.J. (CBSNewYork) — The ATF and the FBI are conducted a raid on a building in Elizabeth, New Jersey Monday, which was believed to be the last known address of a man wanted in in connection with the explosion in Chelsea on Saturday.

The FBI swooped down on the First American Fried Chicken restaurant towards an apartment above the fast food joint on Elmora Avenue, which is owned by the family of suspect Ahmad Khan Rahami, 28, WCBS 880’s Sean Adams reported.

Federal sources told CBS News that they believe Rahami is also connected to an unexploded pressure cooker device found near the Chelsea blast, an explosion in Seaside Park, New Jersey and five explosive devices that were found at a train station in Elizabeth, New Jersey.

Linden police say Rahami was taken into custody late Monday morning after officers responded to a call of a man sleeping in a hallway of a local business.

When a responding officer approached the man, the man raised his head and that’s when the officer recognized him as Rahami, Capt. James Sarnicki with Linden police told CBS2.

“The suspect pulled out a gun and fired at the officer and striking him in the abdomen,” Sarnicki said. “The gentlemen got up and started walking down the street in a westerly direction. I’m told that he was randomly discharging his handgun and one of the officers was able to get close enough to him and return fire.”

While authorities believe Rahami is the main person behind the explosions, N.J. FBI special agent Tim Gallagher says law enforcement will leave no stone unturned, WCBS 880’s Kelly Waldron reported.

“Identify the subject and build out their network. And that’s what we’re doing right now along with our partners in federal and local law enforcement,” Gallagher said.

In the meantime, Elizabeth mayor Christian Bollwage says residents should be vigilant, but not live in fear.

“We just have to work harder in making sure that people in our city understand that we’re going to move forward,” Bollwage said.
