Lawyer Ganesh Kanagaretnam, who is representing A Ganapathy's family, has urged the police to release CCTV footage showing Ganapathy being transported in and out of the interrogation room at the Gombak police station.

Ganesh said the footage would show Ganapathy's deteriorating condition every time he was brought out of the interrogation room.

Ganapathy was reportedly arrested on Feb 24 to assist in a probe linked to his brother who was wanted by the police. On March 11, the deceased's mother, S Thanaletchumy, claimed that her son was beaten while in custody.

The claim was made after she was contacted by a police officer on March 8, only to be informed that her son was freed and being treated at Selayang Hospital's intensive care unit.

Ganapathy died in hospital on April 18.
