A top official in the department said that the separate team was formed to help nab Chanuka faster.
The Lankan constable, Pradeep Kumarapandara, was brought to Dhanushkodi by a CB-CID team led by Deputy Superintendent of Police Raju.
Earlier, the team questioned Sivakami Sundari’s house owners, neighbours, parents, ex-husband at the CB-CID office in Tallakulam.
The parents of Advocate Sivakami Sundari said that it was the Madurai-based lawyer who first raised suspicion over the death of Sri Lankan underworld criminal Angoda Lokka.
Sivakami Sundari, her associate Thiyaneshwaran from Erode, and Lokka's girlfriend Amani Dhanji were arrested on August 2 for forging documents, including Aadhaar, for Angoda Lokka.
The hearing on a bail plea of Sivakama Sundari was postponed to August 19, said officials.
