SINGAPORE - The elderly man who suffers from Alzheimer's had the shock of his life when he opened the mail last year.
He was looking at obscene photos taken of his then 23-year-old daughter.
And the man who sent it claimed to be the gay, HIV-infected ex-lover of his daughter's boyfriend.
There were also lewd descriptions of his daughter, insinuating that she was promiscuous, among other allegations.
Unable to accept what he had just seen and read, the father, now 71, broke down in tears.
The police were called.
On Wednesday, Low Peng Hu, 49, the girl's former lecturer, was jailed three weeks for sending the obscene photos to her parents.
Low had started out being a concerned lecturer and ended up having an affair with the former student, even though they did not have full sexual intercourse.
