In order to find a comedian living in New York who made light of the missing Malaysia Airlines flight MH370, Malaysia is asking Interpol for assistance.
Police say they are looking into Jocelyn Chia, a US citizen who was born and raised in Singapore, for violating laws against incitement and offensive online content.
Following the publication of her joke online last week, Singapore and Malaysia both issued formal statements of regret.
In March 2014, MH370 vanished shortly after takeoff from Singapore.
The plane's main body was never discovered, despite a four-year search in the Indian Ocean. The 239 passengers on board are all assumed dead.
Acryl Sani Abdullah Sani, the head of Malaysia's national police, announced on Tuesday that a request would be made to Interpol to learn Ms. Chia's "full identity" and "latest location.".
The argument started when she published a clip of her most recent stand-up performance at Manhattan's Comedy Cellar club.
It featured a skit about the long-standing rivalry between Singapore and Malaysia, which were once briefly united under one government.
She made fun of Malaysian airplanes, remarking that Singapore was now a "first-world country" while Malaysia was still "developing".
"Malaysian Airlines going missing not funny huh? Some jokes don't land," Ms. Chia continued. ".
TikTok removed the video after it caused a stir in Malaysia, citing a breach of its hate speech policies.
Ms. Chia did not speak for Singaporeans, according to Singapore's ambassador to Malaysia. Foreign Minister of Singapore Vivian Balakrishnan denounced her "horrendous statements.".
As of Sunday, Ms. Chia told CNN that she had successfully completed the routine "more than 100 times.".
She continued, "I stand by the joke, and the clip was taken out of context."
