2:15 p.m.

Federal prosecutors have charged a New York City man with buying illegal guns from an undercover agent as part of a planned terrorist attack on Times Square.

Prosecutors said in court papers made public Friday that 22-year-old Ashiqul Alam spoke about terrorist organizations including ISIS during months of conversations with the agent.

They said he “repeatedly expressed interest in purchasing firearms and explosives for a terrorist attack in the New York City area.”

Alam is in federal custody awaiting arraignment. Alam’s lawyer, James Darrow, declined comment.

Prosecutors say he was nabbed in a sting in which the undercover officer sold him a pair of semiautomatic pistols with obliterated serial numbers.

According to court papers, Alam and the undercover agent made a trip to Times Square in January and recorded video of the area.

Authorities have arrested a New York man who talked about wanting to throw a grenade in Times Square.

Two law enforcement officials told The Associated Press the man was placed under investigation over the comments, and then arrested late Thursday after trying to buy a weapon.

He’s facing weapons-related charges.

The officials spoke on condition of anonymity because the charges hadn’t been made public yet.

They called the man’s statements “aspirational” and never reached a stage that endangered the public.

The man is expected to be arraigned Friday at a federal court in Brooklyn Friday.

Times Square has been a target of attacks before. An Islamic militant tried to detonate a car bomb there in 2010.

In 2017, a man detonated a bomb in a tunnel linking the square to a bus terminal.
