Along State St. after turning off Osborn St., demonstrators tripped one police officer who got ahead of his formation. This lead to a brief scuffle in which some NAC members threw rocks at police as they charged the crowd, injuring one girl with cuts on the head.

Of the 15 later reported injured, three were treated in Cambridge City hospital, five in the M. I. T. infirmary, two in Mt. Auburn hospital, and five at the NAC medical center. All injuries were minor, including the one girl injured in an auto accident during the demonstration, who was apparently pushed against a car.

Police chased a band of demonstrators into the industrial sector of Cambridge south of Mass Ave., but left them to wander back to the M. I. T. student center.

Cronin said that seven arrests had been made, but according to Cambridge police there was only one-an M. I. T., student identified as Allan Fuchs who was charged with unlawful assembly and disorderly conduct and brought before the East Cambridge Court. He was released on $1000 bail for a later hearing.

At his afternoon press conference, Gray called the police performance a "disciplined action." He said that as yet no names of M. I. T. students had been taken down for possible school discipline.

Gray added that both the Center for International Studies (CIS) and the administrative offices-targets of Tuesday's protests-were operating normally with the exception of President Howard W. Johnson's office which was not occupied "because the president had moved elsewhere on the campus." He refused to say where.

The militant picket line was the least militant action discussed at an all-night NAC meeting Tuesday night, and the only proposal to pass when a vote was taken at 3:25 a. m.
