Human remains dumped in bag

A duffel bag containing human remains was found outside a US biotechnology building in Cambridge, Massachusetts on Saturday morning, and one person was later arrested in connection with the grisly discovery, authorities said.

The duffel bag was found shortly before 8am near a building used by biotechnology company Biogen Inc and a block from a police station, Middlesex District Attorney Marian T Ryan said.

Video surveillance of the area led police to an apartment building across the street, where additional human remains were found in a common area, authorities said.
