Businessperson Yong Chee Kong has been questioned by police in Sabah over his offer to donate two million doses of a Covid-19 vaccine to Penang.

Sabah police commissioner Hazani Ghazali said police were investigating the case but did not say whether Yong would be arrested.

"Yes... this morning my officer will be recording his statement," Hazani was quoted as saying by The Star.

It was not clear what aspect of the donation offer is being investigated.

Yong is a Malaysian who works for Xintai Enterprise Development Ltd - a company based in Hong Kong.

According to reports, he had initially offered to donate the Sinovac vaccines to the Sabah government, which rejected his offer as the vaccine had not yet been approved by Malaysia.

Yong claimed that the Penang government then approached him about getting the vaccines.

Yong's attempt to donate the vaccines came to light after the minister-in-charge of Covid-19 vaccinations, Khairy Jamaluddin, dismissed the offer as a scam.

This was due to an error in the spelling of the company's name in a letter allegedly prepared by Penang DAP on Yong's behalf.

According to a Malay Mail report yesterday, Yong said there was no link to the firm as he was acting in his personal capacity in donating the vaccines and had never wanted publicity.

However, he told The Star that the donation was a "genuine offer by my boss' company based in Hong Kong."
