The noise started some 15 years ago, went away and now appears to have returned.
Residents of Block 312, Bukit Batok Street 32 claim that their neighbour, Madam X, who's in her late 50s, has resumed making loud banging sounds in the wee hours of the morning.
Unable to put up with the noise, neighbours have, since 1998, been petitioning the authorities and their Member of Parliament to resolve the problem.
The noise became less freqient for a while when MP Amy Khor, Residents' Committee members and HDB officers spoke to Madam X, but it picked up again in January.
When approached by social workers to seek treatment at the Institute for Mental Health, Madam X refused.
Neighbours are now petitioning to have her evicted.
