Student members of Harvard's security force moved closer yesterday to forming a representative body to deal with University police officials in labor-related matters.

Roughly half of the 100 members of the force signed a petition last May urging that such a committee be formed, in an effort to increase their influence in the police department policies.

Nearly 50 security patrol members met last night, and decided to form the liason committee formally in two weeks.

Gikas Hardouvelis '78, a student patrol member, said last night the student committee would consider the prospect of differential pay. All student members are now paid $3.40 an hour.

William A. Lee, acting chief of the University police, said he welcomed the formation of the committee and that he will "be available at any time to discuss the issues the committee brings up."

The committee may hear the disciplinary cases of security force members and train members who are new to the force, Vivek Haldipur '79, a student patrol member, said yesterday.

Both the police administration and the student guards agreed yesterday that the liaison committee could create a two-way channel of communication, and improve the overall performance of the security force.

Lee said he believes it is important for the force to work continually to improve itself, as it must compete with other professional security groups for contracts with University buildings, and for the jobs of the 35 professional guards the University now hires.

Those 35 guards will only be replaced after they leave on their own or retire
