As the investigation continues into the New Jersey man arrested in connection with Saturday night's bombing in Chelsea, the man's father reportedly said he alerted authorities about his son's potentially destructive path.

The New York Times reports that two years ago, Ahmad Khan Rahami's father told police his son was a terrorist, which put him on federal agents' radar.

The Times cites two senior law enforcement officials who said the father made the statement to New Jersey police in 2014, when Rahami was arrested after a domestic dispute, and charged with stabbing his brother.

Speaking to reporters Tuesday, the father said he contacted authorities because his son was causing trouble and not because of terrorist motivations.

Meanwhile, law enforcement sources said a notebook found on Rahami contained ramblings about terrorists and also mentioned Anwar al-Awlaki, the Yemeni-American imam who was a spokesman for al-Qaeda in the Arabian Peninsula.

New Jersey State Police got into a shootout Monday with the 28-year-old naturalized U.S. citizen from Afghanistan after receiving a tip about a man sleeping in a bar doorway in Linden.

Two officers were shot. Officer Angel Padilla was out of a hospital Tuesday, while Officer Peter Hammer was expected to possibly leave later in the day.

Rahami remains hospitalized and faces five counts of attempted murder of a police officer.

Surveillance video allegedly shows Rahami on 23rd Street in Chelsea Saturday night, just hours before the explosion that injured 29 people.

The FBI said he is also directly linked to an explosion earlier in the day in Seaside Park, N.J.

Federal charges for the explosions are pending. Officials think Rahami acted alone.

Police are still searching for two men seen on surveillance video taking a pressure cooker bomb out of a suitcase, then leaving with the suitcase. Investigators think they left it on the street without realizing it was a potentially dangerous device.
