Ritchie denied any involvement in Manser arrest. On 25 March 1990, Manser was disguised as "Alex Betge" to board MH 873 flight from Miri to Kuching. In the airport, Manser and his friend met police inspector Lores Matios at the boarding area. However, Matios was on his way to take a law exam at Kuching and he didn't notice the disguised Manser on board. Manser arrived in Kuching uneventfully and then took a flight on 26 March to Kuala Lumpur. On 27 March, Swiss ambassador to Kuala Lumpur Charles Steinhaeuslin made a surprise visit to Sarawak chief minister in Kuching. Dealing with Abdul Taib Mahmud In mid-1998, Manser offered an end of hostilities with the Sarawak government if Chief Minister Taib Mahmud would be willing to cooperate with him in building a biosphere around the Penan's territory. Manser also wanted the government to forgive him for breaking Malaysian immigration laws. The offer was denied. His successive attempts to establish communications with Taib Mahmud failed. Manser planned to deliver a lamb named "Gumperli" to Taib Mahmud by air as a symbol of reconciliation during the Hari Raya Aidilfitri celebration. However, the Malaysian consulate at Geneva pressured airlines not to transport the lamb to Sarawak.

There were ten Penan tribe members waiting on the ground to greet Manser. At 11:30 AM, he landed the glider beside a road just outside Taib Mahmud's residence and was immediately arrested. He was then transported to Kuala Lumpur, briefly imprisoned, then deported back to Switzerland via Malaysia Airlines Flight MH2683. Manser was seen playing with his knitted toy lamb by his jailers. By 2000, Manser admitted that his efforts did not bring positive changes to Sarawak. His success rate in Sarawak was "less than zero" and he was deeply saddened by the result. On 15 February 2000, just before his last trip to Sarawak, Manser said that, "[t]hrough his logging
