英语翻译employees who worked on the tenth floor escaped by climb

英语翻译
employees who worked on the tenth floor escaped by climbing onto the roof,where students form New York University ,located across the street,stretched ladders over the building
这里的 where students form New York University ,located across the street,stretched ladders over the building
该怎么分析呢?where是 修饰 roof的么?还有,loacated acress the street 是不是 修饰 university的 表达沿着街道坐落的university 这个意思
整个文章 翻译的话 应该是怎样?
