The safety and needs of a prisoner are not the only concerns. The safety and needs of the victims and public are also a concern. Moreover, if there was a breach of security (which is at least close to the definition of what happened), temporarily securing the prisoner in a separate location to assess what happened and how it happened doesn’t immediately strike me as unreasonable.
I would prefer, of course, that it wasn’t solitary.
