On Saturday, police took 18-year-old Brianna Brochu into custody on charges of third-degree criminal mischief and second-degree breach of peace, MassLive reports. The arrest comes after an Instagram post was found on her account saying that she spent the past month and a half secretly abusing her roommate. In the post, the freshman allegedly admitted to "putting moldy clam dip in her (roommate's) lotions, rubbing used tampons on her backpack and putting her toothbrush places where the sun don't shine." At one point in the post, her roommate is referred to as "Jamaican Barbie."
