Two people are still hospitalized as a result of Monday's confrontation at Phillips Brooks House, and one man has been charged by Cambridge Police for possession of a dangerous weapon.

Five other people were treated Monday night at Cambridge City Hospital for stab wounds after fighting broke out at PBH between members of the National Caucus of Labor Committee (NCLC) and a group of people identified by Cambridge Police as members of De Mau Mau, a black Vietnam veterans group.

Neither group is Harvard related and no Harvard students were apparently involved in the clash. PBH rented the room to the NCLC for Monday's meeting.

Thomas Perry and Paul Goldstein-- both of New York--were still listed in "fair" condition at Cambridge City Hospital last night.

Vincent Terrell of Roxbury was arrested after the meeting and charged with possession of a dangerous weapon after police took an automatic pistol with an altered serial number from him.

Officer Frank Calogero of the Cambridge Police said yesterday that Terrell identified himself as an educator at UMass at Boston. UMass information has no listing for Terrell.

The meeting had been called Monday night by the NCLC to discuss what they claim are connections between Imamu Baraka (Le Roi Jones) and the CIA. The NCLC says that Baraka is a paid agent for the CIA.

NCLC guards had been searching everyone who entered the third floor room at PBH before the meeting began. "We expected De Mau Mau to come," Linda Bankes, a member of NCLA, said yesterday. Bankes said that the black group had violently disrupted their meetings before. She cited another con- frontation about four weeks ago at a public meeting at UMass at Boston.

At about 8 p.m. Harvard University Police arrived at PBH and insisted that NCLC stop searching people coming into the meeting. Dean Epps indicated late Monday night that the police might have been telephoned.

Bankes said that members of De Mau Mau had called the University Police to stop the search for weapons. University Police Officials had no comment yesterday. No member of De Mau Mau could be reached yesterday for comment.

The fighting broke out at about 9:30 p.m. after several men in fatigue jackets entered the meeting and began shouting at the speakers on the platform. A PBH spokesman said yesterday that PBH had only rented the room to the labor group. "We have nothing to do with them," she said.

Dean Epps said yesterday that he had met with the Executive Committee at PBH to talk about the use of the building by outside groups. He said that they will not grant permission for meetings again to the NCLC because of the danger involved. He said that a review was underway to determine future policy on renting rooms to outside groups
