Sangkari Pranthaman said this should be done because it was based on the information provided by her brother that another alleged drug trafficker, Zamri Mohd Tahir, was arrested.
Pannir, 34, who was granted a stay of execution two years ago, failed in his appeal on Nov 26 to start a court challenge against his death sentence.
“I would like to point out that Zamri was arrested in October 2014, after Pannir was arrested in September 2014,” Sangkari said in a statement. “What was the CNB doing before September 2014? Why was Zamri caught only after Pannir’s arrest?”
If the CNB had intelligence on Zamri before Pannir’s arrest, as it had told the court, why was he not arrested sooner, she asked.
“I urge the CNB to be more transparent on how they caught Zamri and we want the prison and judicial system to bring Zamri and Pannir to the courts for a hearing, along with the CNB,” she said.
Sangkari also took aim at Singapore senior state counsel Francis Ng’s statement that Pannir had failed to identify Zamri from photographs presented to him during the investigation into Zamri.
“How can a drug mule who has been arrested be able to identify the person he is supposed to send a parcel to? It goes without saying that Pannir did not recognise Zamri’s face as they are not friends or acquaintances.”
She claimed that Pannir still provided investigators with important information such as Zamri’s home and work addresses, his phone number, the address of the drop off point and his own mobile device.
“I strongly believe that information provided by Pannir must have been used by the CNB in some way.”
She also claimed that when Pannir met Zamri in Changi Prison, Zamri told him that “an Indian guy” provided information that led to his arrest, which she said pointed to Pannir’s role in his capture.
Pannir was arrested in 2014 for importing in 51.84g of heroin into the republic and convicted and sentenced to death in 2017. A number of his appeals had been denied but he was able to secure a two-year stay the day before he was set to be hanged.
