In 1986 and 1987, there was a rash of "butcher-knife robberies" in the Tainan-Kaohsiung area. The robber's modus operandi was to break into homes, use a telephone cord to tie up the man of the house, and then demand money. The perpetrator often raped women in front of their husbands.
例如民國七十五、六年間橫行在台南、高雄一帶的菜刀大盜，作案的手法是：以電話線將男主人綁起來以菜刀威脅要錢，或在男主人面前將女主人強姦。
