Deputy Comm Mohmad Salleh in a statement said two suspects taken into custody last night, aged 35 and 40, are believed to be involved in the murder R. Karikaalan late last month.
"We cannot confirm whether these two are the main suspects. However, we believe they are involved in shooting Karikaalan," Salleh said.
The duo have been remanded to custody until May 15.
On April 26, Karikaalan, who worked as a barber, was driving home in his car when two men on a motorcycle fired several shots inside.
She was shot in the arm but survived.
