BOULDER (KDVR) — Boulder Police have confirmed two separate but ongoing sexual assault investigations that reportedly happened at the same off-campus fraternity house.

In response, students are holding a march Friday evening to call attention to the need for more action on sex assaults among students.

According to police, each case happened at a fraternity house in the 1000 block of 12th Street. The first sexual assault was reported to have occurred late Oct. 23/early Oct. 24. The second sexual assault reportedly happened on Oct. 31.

Police did not say which fraternity house was involved, but students who spoke with FOX31 said it happened at the Pi Kappa Alpha house. The march on Friday will lead to the outside of the Pi Kappa Alpha house, according to a digital flyer shared with FOX31.

In a statement Boulder police say:

The Department takes all such reports seriously and are unable to release further details at this time without compromising the integrity of the investigations.
