CAMBRIDGE, Mass.—Transit police in Boston were investigating a shooting on a subway platform at Harvard University on Sunday that prompted the school to issue a shelter-in-place order for students and staff.

Authorities temporarily rerouted passengers on part of the city’s subway system to shuttle buses as officers from various departments searched for a suspect.
