Chennai: A special court here on Sunday remanded to 15-day judicial custody a retired senior army officer who was arrested for allegedly killing a 13-year-old boy at army premises here.

Lt Col Kandaswamy Ramraj, charged under Section 302 of IPC (relating to murder) was produced before the Georgetown Special Court and remanded to 15-day judicial custody, sources said.

Early in the day, the Tamil Nadu Police crime branch which was investigating the case, said it had arrested Ramraj for killing the boy last Sunday when he had entered the army premises to pluck almonds.

The weapon -- an imported 0.3mm rifle used by the 58-year-old suspect and the car he used were also seized by the police, CB (CID) ADGP R Sekar had said.

Dilshan, residing in the Indira Gandhi Nagar locality adjacent to the army quarters in the Island Grounds locality, fell victim to a mysterious bullet when he tried to pluck almond fruit from the army residential area.  The victim's family had alleged he was shot by Army personnel.

The postmortem report had earlier established that a bullet injury had killed Dilshan when he scaled the Army campus.

An army officer in the rank of Lt Colonel and some others were questioned in the past few days in connection with incident.

Condemning the incident, Chief Minister Jayalalithaa had said the teenager was killed by an army jawan and had written to the General Officer Command requesting that the culprit be handed over to the state police.
