On 24 October 1968, Adams, fearing an occupation and growing support by the students for the anti-Vietnam War demonstration on 27 October, decided to close the LSE for the weekend. As this questioned the right of the administration to close LSE against the wishes of lecturers and students, the move led to 3,000 students occupying. During the occupation, the School was policed against intruders, and cleaned; teach-ins and discussions were organised; and medical services were set up and staffed. The occupation ended that Sunday night.
