The attempted murder charge against Baldev Singh Kalsi, the former leader of a Sikh temple in Surrey, B.C., was upgraded today to second-degree murder after his wife, Narinder Kaur Kalsi, was taken off life support, police said.

The woman died after her family agreed to have her taken off life support on Sunday afternoon, police have confirmed.

On July 13, she was taken to hospital in critical condition after she was found in severe medical distress at her family home in South Surrey.

On Monday, police confirmed charges against her husband had been upgraded.

Baldev Singh Kalsi was arrested at the scene and originally charged with aggravated assault, and then attempted murder.

Last week, police confirmed he was attacked by another inmate at the pretrial facilities in Surrey.

He was president of the Brookside Sikh Temple in Surrey at the time of his arrest, but has since been removed from that position.
