BOSTON (CBS) – Two female Boston University students each spotted someone trying to take pictures of them while they showered in two separate incidents last month.

The incidents occurred in the same dorm building at 273 Babcock Street on Jan. 22 and Jan. 25.

In the first incident, a woman saw a suspect holding a Blackberry under her while she showered at around 12:30 p.m.

WBZ-TV’s Kate Merrill reports.

The suspect in the second incident held an iPhone while a different woman showered at around 8 a.m. on Jan. 25.

Police aren’t sure if they are seeking one or two suspects. Beyond the type of phones used, police don’t have a detailed suspect description.

Anyone with information is asked to call BU police at 617-353-2121.
