"It was a frenzied, mad attack. You would not imagine the damage a pair of tiny eyebrow tweezers caused the poor girl," an unidentified police officer told the Daily Mail in a story published Monday.

Kristina Danilova, 18, allegedly flew into a rage after her childhood friend, Olga Samoilenko, 18, told her she was ugly and would never get a boyfriend, the Mail reported.

Police said Samoilenko was stabbed more than 100 times with the tweezers and bled to death, the Mail reported.

Danilova, who allegedly called the stabbing an accident and then told police she didn't remember the attack, remained in custody Sunday, the Mail reported.
