Miri Fire and Rescue chief Law Poh Kiong said Nigel Bevan had sustained serious head injuries in the incident which occurred along “Pinnacle Trail” at 9.07pm.

He said the Mulu Park search and rescue team managed to bring Bevan to Camp 5, where the department’s air unit team and a doctor is based, before he was rushed to Miri Hospital for further treatment.

“The victim was already unconscious while being brought down at 2.28am,” Law said.

Marudi police chief DSP Gabriel Risut had earlier said he could not elaborate on the case as the incident was initially reported via an email from Mulu World Heritage Park manager Hein Gerstner to Sarawak Fire and Rescue assistant director (operations) Tiong Ling Hii in Kuching.
