Panna Ismail, Bilal Malik and Fakruddin alias 'Police' Fakruddin, were brought to Puttur on a transit warrant from Vellore jail in Tamil Nadu under tight security and were produced before the Judicial First Class Magistrate (JFCM) court, police said.
"They were produced before the JFCM court and shown as arrested. The court sent them to judicial custody and they were taken back to Vellore jail," Puttur Circle Inspector S Chandrasekhar said.
An Inspector was injured when he entered the house in disguise and was pulled in by the suspected militants while Ismail suffered bullet injuries when police fired in self- defence.
Malik's wife and three children (who were with the accused during the operation) safely came out later.
Apart from 2011 Advani pipe bomb case (attempt to kill BJP veteran LK Advani), the arrested are believed to be involved in about half-a-dozen major crimes, including in the murders of BJP and Sangh Parivar unit leaders in Tamil Nadu.
