SINGAPORE - A housewife with a codeine dependency, who duped 18 doctors into giving her cough syrup containing the drug, was sentenced on Friday (Jan 13) to a mandatory treatment order (MTO) for year.

An MTO is for offenders who suffer from psychiatric conditions. They must go for psychiatric treatment in lieu of jail time.

Eileen Siak, now 33, pleaded guilty in court on Nov 17 last year to seven counts of cheating involving $265.

Fourteen other cheating charges involving $260 were taken into consideration during sentencing.

She must now seek treatment at the Institute of Mental Health, the court heard.

To obtain her fix, she impersonated several women between April 23, 2014 and March 4, 2015 to cheat the doctors.

Siak used to work for a wellness company between 2009 and 2011.

As an accounts manager , she received a customer database, which contained their personal particulars.

She saved it in her private e-mail folder instead of the company's e-mail account, and then used the customers' details to register for appointments at polyclinics.

Posing as them, she obtained her supply of cough medicine between April and August 2014, and the last time on March 4, 2015, even though she did not have a cough.

Initially, she paid for her medication but she later decided to walk away without paying.

The court heard she frequented two National Healthcare Group Polyclinics (NHGP) in Bukit Batok and Jurong.

Her crime spree ended after an NHGP senior manager made a police report on March 16 2015.

Siak's lawyer Josephus Tan had said his client has been suffering from codeine dependency since June 2013.

For each cheating charge, she could have been jailed up to three years and fined.
