Two of the seven men charged over a slashing case which left a restaurant manager with a disfigured face were each accused yesterday of threatening the man.

Singaporean businessman Zackeer Abbass Khan, 45, alleged to be the mastermind behind the attack, is accused of threatening Mr Liakath Ali, 52, four days before the incident by uttering in Tamil to him to "watch out, in one week I will do you".

His alleged co-conspirator, Indian national Koleth Navas, 29, allegedly told Mr Liakath: "I have your photograph in my mobile phone, you watch out."

The alleged threats were made outside the Singapore Zam Zam Restaurant, in North Bridge Road at about 6.45pm on Aug 22.

The duo are accused of abetting in a conspiracy with Anwer Ambiya Kadir Maideen, 46, to grievously hurt Mr Liakath between Aug 22 and Aug 26.

Court documents say three Singaporeans - Joshua Navindran Surainthiran, 22, his brother Joel Giritharan, 24, and student Ramge Visvamnathan, 19 - slashed Mr Liakath's face with a knife - in Arab Street at about 10pm on Aug 26.

Joel told District Judge Eddy Tham that he and Ramge were not liable for the attack and just happened to be there.

No bail was offered to Joshua, who jumped bail in November last year. He has outstanding matters before the court.

The prosecution applied for three weeks' adjournment to complete the investigation and consult the Attorney-General's Chambers.

Bail of $50,000 was offered to Khan. Koleth Navas, Anwer and Joel were allowed bail of $40,000 each, while Ramge's bail was set at $20,000.

The seventh man, Indian national Koleth Abdul Nasir, 41, faces one charge of threatening Mr Liakath outside Zam Zam. His bail was also set at $40,000.

Their passports have been impounded. They have to report to the investigation officer every Wednesday morning if they are out on bail.

All except Joshua are represented by counsel. They will be back in court on Oct 21.
