HOLYOKE, Mass.--Police arrested 45 people, including 20 University of Massachusetts at Amherst students for trespassing after notice" and disorderly conduct last week during a protest sit-in-art U.S. Representative Silvio Conte's office in Holyoke.

The group calling itself the February 11th Coalition staged the protest to pressure Conte (R-Pittsfield) into nothing against an additional $55 million in aid to the El Salvadoran government as requested by the Reagan Administration said Sarah Kemble a member of the coalition.

The arrests were conducted in an "orderly manner" and the majority were released on personal recognizance with no but charged, said Holyoke Police Officer John Craven. A few of those arrested chose to stay overnight rather than pay the $15 release fee charged in cover processing costs. Craven added. Arrangement will be on February 25.
