 The son-in-law Of Libau "Rentap" named Layang was known to be the first Iban to kill (bedengah in Iban) a British officer in Sarawak by the name of Alan Lee at the battle of Lintang Batang at the newly built Skrang fort.It was this incident that caused the Brooke to refuse pardon or accept Rentap's surrender like the other Iban chiefs during that time, notably the sons of Orang Kaya Pemancha Dana "Bayang" by the name of Nanang and his second brother Luyoh who turned rebels against the Brooke government for killing their third brother Ajie at the battle of Sungai Langit in Padeh.Nanang was later appointed Orang Kaya Pemancha to replace his father, for his surrender and his assistance to defeat his fellow Iban chief Libau "Rentap" at Sadok Hill who he followed just before that surrender.
