JOHOR BARU: The group of 22 Malaysians who went on the ill-fated tour to Chiang Mai were mostly senior citizens in their 50s and 60s.
Chiu Travel Sdn Bhd general manager Terence Yung, who handled the group on the five-day tour, said they were either family members or close friends.
"The group left Singapore by flight to Chiang Mai and went on a sight-seeing trip around the city and Chiang Rai on Thursday. They were supposed to return on Monday," he said.
Yung said the agency was alerted of the tragedy by the Thai authorities at about 4pm yesterday.
"We have already contacted the next of kin, but we have yet to get a full report on what really happened, and there have also been conflicting reports.
"Our priority now is to sort out the list of travellers for identification purposes," he added.
In a Facebook posting, the agency said the injured were sent to five hospitals in Chiang Mai and that it was working to get the full list of their names.
It said that it would provide its fullest assistance to the family members.
Yung said family members could contact Chui Travel office here at 07-433 5599/07-433 5588 and 07-431 5797 for updates.
