Raveendran’s name surfaced in the statement given by Swapna Suresh, a key accused in the gold smuggling case.
According to the court, the modus operandi and how Sivasankar used his official powers to abet the crime need to be investigated.
As part of enforcing the order, the customs team visited the Viyyur Central Jail on Wednesday morning and handed over the copy of the detention order to the Jail Superintendent.
Earlier this month the first notice was issued, but Chief Minister Pinarayi Vijayan's Additional Private Secretary, CM Raveendran, did not turn up as he had tested positive for COVID-19.
According to the prisons department, investigation agencies other than NIA, customs and the Enforcement Directorate cannot interrogate Swapna directly.
In the wake of Sivasankar's arrest by the Customs, the National Investigation Agency probing terror financing behind the gold smuggling incident will also conduct an investigation into his role
Customs officials said they will visit Sivasankar at Kakkanad District Jail to record his arrest on Monday evening or Tuesday
The Crime Branch can commence an investigation only after registering an FIR and this means Swapna has to be interrogated to get details about the clip.
A three-member advisory board comprising High Court judges was formed to review COFEPOSA detention in the case.
A Special Investigation Team of the crime branch has been entrusted to conduct the preliminary enquiry, police sources said.
The move is an effort from the part of the Pinarayi government and the LDF to sabotage the probe on the gold smuggling case, the Congress leader said.
On Thursday, the prisons department conducted a preliminary inquiry and submitted a report to Rishi Raj Singh.
The court will consider his bail plea on Monday. A senior Supreme Court lawyer is likely to argue for Sivasankar.

The report also suggested police probe to find out the source of the clip as the preliminary probe ruled out the possibility of recording the clip at Attakulangara women's prison.
Swapna Suresh was heard saying that the investigation officers offered her to become an approver in the case if she falsely claimed chief minister's link in the case.
