As the Justice Department released some of the first information on the 80 immigration detainees, there was new word about a Saudi man detained in Washington since the day of the suicide hijackings Sept. 11.

And Attorney General John Ashcroft visited the scene of devastation in New York to deliver $10 million in fresh police aid. Officials nationwide continued the heightened vigilance against new terrorist attacks.

''I don't want to scare people or put fear in the minds of people, but this is very serious business. It's not a matter of if, but when,'' said Sen. Pat Roberts, R-Kan., after attending an intelligence briefing on Capitol Hill.

The investigation made gains across the globe.

In London, authorities arrested three men and one 25-year-old woman in connection with the World Trade Center attack, and they were being questioned by anti-terrorist police, Scotland Yard said.

French authorities arrested seven people in connection with an alleged plot to harm U.S. sites in that country.

German prosecutors issued arrest warrants for Ramzi Binalshibh, 29, of Yemen, and Said Bahaji, 26, a German of Moroccan origin, in connection with the Sept. 11 plot.

Both are suspected of helping plot the attacks on New York and Washington with three hijackers who lived for a time in Hamburg, Germany, prosecutor Kay Nehm said. He said they are being sought on charges of forming a terrorist organization and at least 5,000 counts of murder.

In Washington, the Justice Department released documents charging 33 of the 80 people taken into custody by immigration authorities.

The names of those detained were covered up in the documents. Their native countries included Egypt, Israel, Pakistan, Jordan, India, Saudi Arabia and Syria.

Department officials have said some of those detained may have information about the plot for the attacks or about the 19 suspected hijackers.

Some, but not all, are cooperating with investigators. None has been charged with a crime directly related to the attacks. All 33 of the detainees are still in custody. They can be held for as long as the government deems necessary.

Seven of the detainees came into the country illegally, authorities said, five into Texas, one into Washington state and one at another location on the U.S.-Canada border. The only non-Middle Eastern detainee, from El Salvador, entered the country illegally, authorities said.

Among the 33, six were Egyptians, five were Jordanian and four were from Israel. One Israeli was a native of Jordan.

Meanwhile, authorities and a lawyer confirmed that a Saudi man was arrested on the day of the attacks in suburban Washington, a few miles from Dulles International Airport, where one of the planes was hijacked. That plane later crashed into the Pentagon.
