Last year, the Tampines Town Council put up notices with images of two culprits taken from closed-circuit television footage after several complaints by residents at Block 366, Tampines Street 34.

One of the pictures showed the back view of a man smoking in a lift at about 5am on Jan 14.

The other showed a bare-bottomed woman squatting and, it is believed, urinating at around noon on Jan 15.

The images were blurred.
