However, she said the doctors were not linked to the case of the houseman who fell to his death from an apartment at Jalan Datuk Keramat last month.

“I have sent the names of five doctors alleged to be bullies at Penang Hospital to be studied by the (health) minister, and Khairy Jamaluddin has responded.

“The names submitted are not related to the case of the death of the trainee doctor because this case is still under police investigation,” she said, according to a report by Kosmo.

She said the names were handed over because they were alleged to be “the most toxic ones”.

“I handed over the names after reading that the Negeri Sembilan health exco did this by handing over two names to the health minister,” she said.

It was reported that the houseman fell to his death from the 23rd floor of his rented apartment building on April 17, just three weeks after being posted to Penang Hospital.

Last week, the health ministry said it would form an independent task force to investigate the incident.

Khairy said the task force would also investigate the culture of bullying which housemen and junior doctors had alleged.

He also said he had received a report from the relevant department head at Penang Hospital, and confirmed that police were also investigating the incident.
