Investigation of the Tai Mo Shan rape was going nowhere until an unrelated murder case provided an unexpected breakthrough. Police had been trying to narrow down suspects by seeking South Asian men of a similar height and build as the attacker, but this still left 'a few thousand', said senior inspector Chan Long-yeung. Then police started another investigation in the South Asian community after the charred body of an insurance agent was found in a suitcase in Yuen Long. 'We pinned the defendant as a suspect for the murder case, while his DNA sample showed that he was involved in [the rape] case instead,' Mr Chan said. Police found him in a private vehicle during a routine road block in Yuen Long on October 9. 'It was more difficult to get to him than a local citizen, because the minority groups in Hong Kong tend to move about the territory,' Mr Chan said. Muhammad Faryad, a casual construction worker since he arrived in the city in 1996, also worked in his uncle's trading company but was unemployed at the time he committed the rapes. Michael Yuen Man-fai, administration manager of the Hong Kong Youth Hostel Association, said the Sze Lok Yuen Youth Hostel, where the rape victims were staying, had installed more lights near the entrance after the incident but would not hire security guards to patrol the area at night. The association controls seven youth hostels in the city, all in remote areas.
