A mother bit off an attacker's tongue and carried it in her mouth all the way to her home to ensure his capture.
Adele Barber, 29, was walking in an alleyway near her home when a man brushed past her.
Moments later, he ran back, pushed her against a wall and assaulted her, despite it being broad daylight.
Barber, who had been a victim of rape in the past, had enough clarity to realize she could fight back.
"[I was] more determined this time," she explains, "I thought 'I've got to get evidence and show this is not consensual. No one is going to do this to me again. I'm going to make sure this person gets the treatment they need.'"
"I wanted to get DNA and cause pain to get him off me. I didn't think I would bite off his tongue, I thought I would just get his DNA on my teeth," she continued.
