Firdaus was deemed to have breached the provisions of the Code of Conduct & Professional Ethics after a night out with friends ended in a police investigation.
According to a statement on the events provided by the FAS, Firdaus's fiancé, his childhood friend and himself had all gone to Clarke Quay to celebrate his belated birthday on February 4, 2012.
After some drinks the player is understood to have felt high and also felt like vomiting. As he was being helped to the toilet, his friend picked up a lady's handbag thinking that it belonged to Firdaus's fiancé. Firdaus and his friend were detained by the police for investigation and that accounted for his absence from training the following day. The police are continuing with their investigation.
Firdaus denies any involvement in any offence.
The FAS has suspended Firdaus for breaching their code of conduct which prohibits the consumption of alcohol at any time.
"FAS is of the unwavering view that the irresponsible conduct of Firdaus cannot be tolerated. There is absolutely no compromise for the exemplary conduct of players and officials who are contracted to FAS and playing for the LIONSXII team," read a statement from the FAS.
"We will not hesitate to take appropriate action if any player is found guilty of breaching the team's code of conduct. Firdaus will be suspended from all football activities for breaching LIONSXII Code of Conduct Section 1b, 1d and 8f until the FAS Disciplinary Committee convenes and its members deliberate on the matter and decide on the appropriate action to be taken.
"We understand that Firdaus is now assisting the police in the investigation of an alleged offence and we will await the conclusion of the case. Firdaus has informed us that he is not involved in the alleged offence and he assured us that he will cooperate fully with the authorities during the investigation. However, should Firdaus be found guilty of the alleged offence, we will subsequently decide on what further action to be taken including termination of his contract."
Firdaus has issued an apology via the FAS in which he expressed "deep regret" over his actions and that he "will accept the punishment meted out by the FAS Disciplinary Committee."
