Seattle Public Schools will keep working with the groups that were holding classes in the vacant Horace Mann school building, the district said after police arrested four people for trespassing on Tuesday.

District officials said those who set up barricades earlier this month and refused to leave were just a small subset of the group that had been using the building over spring and summer.
