PORTLAND, Ore. (AP) — Police say three teenagers assaulted a transgender 20-year-old and stole their phone. The Oregonian/OregonLive reports the person told police that while walking along the river near Boones Ferry Park, they crossed paths with three male teens, one of whom called them a transgender slur. Later, police say the three teens approached and one of them punched the person in the face, police said, while another stole their phone. The victim fell into the Willamette River and swam away but got stuck in the mud while trying to get to shore, police said. They shouted for help and clung onto driftwood until police found them in the river.
