Smell from the flat update
The HDB officer went down and said that the neighbours have seen the occupant of the flat in the mornings. The volunteer said however that she asked around and the other neighbours have said she no longer lives there. She banged hard on the door as she was worried that there might be cats inside - she said that one of the neighbours had seen some cats inside. However, she heard nothing. She does not think the smell comes from cats - and her friends with her think that the smell is of garbage rotting more than anything related to the cats.
She's going back to check again. If we can be quite sure that no one is there then we'll need to get the AVA, police and HDB involved but it's going to be a long drawn out process because THEY will want to be absolutely sure that no one lives there anymore. If we can find out, that will make it easier to get into the flat if necessary.
