Investigators of the Indian ‘Q’ branch police on Tuesday interrogated LTTE operative A Kumaraguru, who police arrested at Trichy airport on July 25 when he attempted to flee to Switzerland with a fake passport.

Officers of the police’s special anti-terror wing said they questioned Kumaraguru — an active operative of the LTTE till the Sri Lankan Army destroyed the outfit with the killing of its chief Velupillai Prabhakaran in May 2009 — about his links to an arrested member of the rebels, Krishnakumar, and his associates in Ramanathapuram.

Police arrested 39-year-old Kumaraguru, originally from North Jaffna, when he attempted to board a Malaysia-bound flight in Trichy last Friday. He told police that he planned to leave to Switzerland from Malaysia.

Investigators said Kumaraguru lost his right leg in the civil war in Sri Lanka and used a prosthetic limb. Kumaraguru and his wife Sudharsini arrived in Chennai in 2014 and lived in Choolaimedu, where a member of a Tamil outfit gave them shelter.

A team led by superintendent of police K Bhavaneeshwari questioned Kumaraguru on his haste to leave India and its connection to the arrest of Krishnakumar and his accomplices Rajendran and Sai Kumar.

The team also questioned Krishnakumar, Rajendran and Saikumar, who were arrested with 75 cyanide capsules and 300 gm of cyanide powder, four GPS devices, mobile phones and Indian and Sri Lankan currency. Krishnakumar has admitted to police that he was one of Prabhakaran’s secretaries.

Police arrested Kumaraguru’s accomplice Thirumurugan and have launched a search for another aide, Mubarak, in Chennai, Times of India reports.
