10 U.S. CITIZENS, 146 ALIENS HELD

Ten American citizens and 146 aliens, all of whom are accused of some form of subversive activity, were held today in the Immigration Service jail. 815 Airport Way, on orders of the Federal Bureau of Investigation.

The 156 persons, whom the F.B.I. classify as "enemies," include six American-born Japanese, two native Americans and two naturalized Germans. The breakdown of aliens is as follows: 116 Japanese, 28 Germans and two Italians.

H.B. Fletcher, agent in charge of the Seattle office of the F.B.I., said two women are among those held.

Under the interned security program instituted by the F.B.I. when war first broke out in Europe, all suspicious persons were investigated and placed in three classes -- those known to be dangerous, those about whom there is little doubt, and those who are merely suspected. Agents said nearly all of those interned here fall in the first two classifications.

It is expected that those being held will be given hearings later to determine disposition of their case.
