Its president Dr Subramaniam Muniandy said they felt the probe was unnecessary and can be seen as “a form of harassment for a simple solidarity campaign”.

“Although MMA is aware that police are allowed to conduct investigations, we strongly condemn the nature of this exercise targeting doctors who have supported our campaign championing the rights of healthcare workers in the country.

“The doctors involved carried out their duties diligently while displaying their solidarity for other healthcare workers,” he said.

Subramaniam said the MMA had briefed the health ministry on its campaign and demands during their last meeting.

“MMA is in the midst of engaging independent legal advice, and will alert the legal authorities with regards to this problem and to provide all support and assistance needed in addressing it,” he said, pointing out MMA had reached out to Kuala Lumpur Bar chairman Vivek Sukumaran for help.

The Black Monday initiative, organised by the MMA’s Section for House Officers, Medical Officers and Specialists (Schomos), encouraged people to change their social media profile pictures to monochrome from July 1 to 12.

Yesterday, people were asked to go to work dressed in black in what became known as Black Monday.
