The allegation about the camps was made by Prime Minister Thaksin Sinawatra of neighboring Thailand and several leaders in his administration, reports Bernama.
"If the Thai government has any information as claimed, it is better that Malaysia be informed confidentially through the official channel. If indeed such camps exist as alleged, we will need to send our security forces to check out the report," Najib said.
Najib said international practice dictates that any exchange of intelligence data not be made public.
He said Malaysia is not considering at the moment the option of sealing off the border with Thailand.
