Bumping this story to the top from my a.m. post on the NYC blasts. A few more details from CNN:

The detainee works at the world body’s weapons inspection agency as an analyst, the official said. Another U.N. source said the man is a satellite imagery analyst.

The FBI is not calling the man a suspect, said spokesman Jim Margolin.

Mayor Michael Bloomberg: “So far nobody reported seeing anybody at the scene,” the mayor said, adding that there had been no warning call before the blast or any call claiming responsibility.

CNN offers another possible target of the attack:

The consulate is on the 9th and 10th floors of the building at 845 Third Avenue, between 51st and 52nd streets.

Other tenants in the 15-story building include The Conference Board, a private firm that compiles several U.S. economic indicators that help gauge the state of the American economy.

The company’s executive vice president and chief economist, Gail Fosler, was the target of an April 14 demonstration by activists against earth-moving equipment maker Caterpillar. Fosler is a Caterpillar board member.

During the protest, demonstrators held signs outside the building claiming that Caterpillar is supporting human rights abuses in the Middle East by supplying equipment used to destroy Palestinian homes.

The protest was part of the International Day of Action Against Caterpillar, organized in the United States by the group Jewish Voice for Peace.

Will be interesting to see how that U.N. employee fits into all of this.

Update: “The New York police and the FBI said the man was not a suspect. Police said he was detained only because he was asked not to cross a police tape and did so anyway. A police official said the man may have been drinking.”
