Various sightings had been reported as early as 1918 in the Vu Quang Nature Reserve of Vietnam and Malaysia and Borneo. These reports indicate the biped is four to five feet tall, very hairy with stout shoulders supporting a leathery neck, and a protruding stomach. The females are distinguished by long pendulous breasts. The cryptids are reported to have a language of unintelligible words.
In 1947, a French colonist reported a sighting and refers to the animal as a L’Homme Sauvage (a Wild Man).
Dr. John MacKinnon claimed to have found the first tracks in 1970, and he believed they were of a hominid origin. He published his findings in a book in 1978 titled “In Search Of the Red Ape”. His findings were co berated in 1984 by Tran Hong Viet a professor of Pedagogic University of Hanoi. He reported finding and casting similar footprints in 1982 to those of MacKinnon’s photographed footprints.
Sightings were also reported in Vietnam during the war by Kregg P. J. Jorgenson in his book “Very Crazy G.I.-Strange But True Stories of the /Vietnam War” published in 2001 by Ballentine Book. The soldiers called them Rock Apes and stated they were approximately five feet tall with a reddish tinge to the brown fur.
In 1971 two Batututs were claimed to have been captured by local tribesmen in the Dak Lak Province which was followed by Hoang Minh Thau, a North Vietnamese General to attempt an expedition to search for evidence of the bipeds in 1974.
