Short on details and long on mystery, the drama continues.

However, long story short:

Yang Yin (pictured above in centre), a 40-year-old Chinese national -- who has been in the spotlight having been accused of taking advantage of an elderly Singaporean widow to gain access to millions of dollars of her wealth -- is under probe by immigration authorities.

Before coming to Singapore, Yang was a tour guide in China. He met an elderly Singaporean Madam Chung Khin Chun, who is 87 now, in Beijing in 2008.

He then came to Singapore in 2009 to visit the elderly woman.

And in 2009, when Yang came to Singapore for four weeks, Madamn Chung together with him set up his own firm, Young Music and Dance Studio, and he was hired by the studio.

In that same year, he visited Madam Chung twice in July and September. He then obtained an Employment Pass to work in Singapore.

Shortly after, in 2010, Madam Chung made a will to leave her assets -- some $40 million worth, including a $30 million Gerald Crescent bungalow -- to Yang.

In 2011, Yang becomes a Singaporean Permanent Resident.

In 2012, he was given Lasting Power of Attorney by Madam Chung, giving him control over her welfare and assets.

In 2013, Yang's family comes to Singapore from China to move into the Gerald Crescent bungalow.

In 2014, Madam Chung, whose husband passed away in 2007 and who has no children, was diagnosed with dementia. Her niece, Hedy Mok, 60, starts court proceedings against Yang to revoke the Lasting Power of Attorney and evicts Yang's 34-year-old wife from the bungalow.

Now, Yang is under probe by the Immigration and Checkpoints Authority as questions have been raised about how he obtained his Singapore Permanent Resident status.

A nameless ICA spokesperson told The Straits Times in an article on Sept. 12, 2014:

"The ICA is aware of media reports on the case and is looking into the matter."

The spokesperson also said:

"Individuals who provide false information in their application for immigration facilities will be dealt with firmly under the law."

Yang also faces police investigation after a report was made against Yang by the Singapore Chinese Chamber of Commerce and Industry for falsely claiming to be the association's director.
