The man, who calls from both a cellphone number and a private number, focuses on older women and has looked at photos of them because he describes their appearances to them, The Star reported.
A 62-year-old woman said the man phoned her after midnight one evening and said he wanted to play with her “tits”.
He told another 70-year-old woman that he “loved her grey hair”.
The women say that the next time the man phones them, they will blow loudly in a whistle just after he speaks.
