Terror suspect Jose Pimentel, arrested by New York City police on Saturday, appeared to have been set off by the Sept. 30 death of al-Qaeda leader Anwar al-Awlaki in Yemen by a U.S. drone strike, Police Commissioner Raymond Kelly says.

Law enforcement had to act quickly to stop Pimentel because he was in the process of making a bomb, Kelly says.

"He was drilling the holes and it would have been not appropriate to let him walk out the door with the bomb, so a decision was made to act quickly," Kelly says.

At one point, Pimentel considered changing his name to Osama Hussein after his heroes, Osama bin Laden and Saddam Hussein, Kelly says.

Jose Pimentel is a native of the Dominican Republic and a convert to Islam who lived in upstate Schenectady, N.Y., for years before moving to New York City, Police Commissioner Raymond Kelly says.

He had long voiced hostilities against U.S. institutions and New York City officials have had their eye on him since 2009, Kelly tells reporters.

On Saturday afternoon, New York City police officers arrested Jose Pimentel, 27, of Washington Heights in northern Manhattan, Mayor Bloomberg tells reporters.

Pimentel, an al-Qaeda sympathizer, had planned to bomb police patrol cars and postal facilities and had a hostility toward U.S. armed services personnel returning from overseas, Bloomberg says.

"The suspect was a so-called lone wolf, motivated by his own resentment of the presence of American troops in Iraq and Afghanistan, as well as inspired by al-Qaeda propaganda," Bloomberg says.
