Having fake degree from a degree mill is acceptable in Singapore?

Below is part of an article posted in the TRE about a staff from IDA with a Masters degree from a degree mill. The netizens are questioning IDA whether this is a crime. So far no official comment from any ministry on this.
 
‘IDA says staff’s MBA not a relevant certificate for her working in IDA
 
On 2 Apr, TRE wrote to IDA for comments on the matter and asked if it is aware that one of their staff has obtained her MBA from a degree mill. TRE did not get any reply from IDA.
 
However, netizens continue to pursue IDA relentlessly on its Facebook page and on Tues (14 Apr), IDA finally replied.
 
IDA said that her Bachelor’s degree is from a reputable university and she was recruited based on the Bachelor degree. Her MBA was “not a relevant certificate for her position in IDA”, it added.
 
IDA further said, “We would like to share that Nisha has been a committed team member and contributed in her role as an Applications Consultant for the past year.”
