A federal appeals court has upheld the conviction and 30-year sentence of a Pakistani man found guilty in an unsuccessful plot to bomb a busy subway station in New York.

The Manhattan court decided that Shahwar Matin Siraj, 25, was treated fairly at his federal court trial.

A jury found him guilty in a 2004 plot to blow up the Herald Square subway station in a congested shopping district where Macy's has long had its flagship store.

Lawyers for the defendant had argued that their client had been set up by a police informant. But the government proved Siraj had shown an interest in radical Islam and violent jihad through books and a videotape.
