Two men from Sarawak, allegedly involved in a spate of violent robberies in 2010, on Thursday went on trial in the High Court for the murder of one of the victims, a construction worker from India.
But the hearing was adjourned after defence lawyers objected to evidence relating to the other robberies being admitted in the murder trial.
The lawyers for Micheal Garing, 25, and Tony Imba, 34, said that evidence relating to the three prior incidents was not helpful in establishing proof and was prejudicial to their clients.
The evidence includes statements given by the accused to the police and witness testimonies.
But the prosecution said the evidence would go to show that they both intended to cause fatal injuries to Mr Shanmuganathan Dillidurai, 41, when Micheal allegedly slashed the Indian national with a parang.
The trial was adjourned to next Tuesday for both sides to make arguments on whether the evidence should be admitted.
Micheal and Tony are accused of being in a group of four men who carried out four violent robberies from the late night of May 29 to the early hours of May 30.
The assaults led to the death of a foreign worker and seriously injured two foreign workers and a Singaporean.
The group were Sarawakians working here.
One alleged accomplice, Donny Meluda, 22, is at large.
