Curry College waited almost a week to tell the campus that a student had reported a "group rape" in a dormitory, The Boston Globe  reported. The victim reported the attack on January 22, three men were arrested on January 25, and the college notified students and others on January 28. A college spokeswoman said that Curry's policy is to notify the campus if alleged assailants are unknown and that in this case they were known. (Two of them are former students.) Curry is now reviewing its policies. A summary of federal reporting requirements  -- by the Clery Center for Security on Campus -- notes that colleges are required to report incidents based on whether a threat may be posed to students, and based on the seriousness of a crime.
