He is survived by his wife and three children. 

Farmers at the protest site told the police that Zile Singh was under depression for the past few days over the fate of the agitation. 

District BKU leader Azad Singh said Zile Singh was alone at the protest site when he committed the suicide at night. 

In the morning when farmers arrived at the protest site they found him lying on the bed in an unconscious condition. A bottle of poison was recovered from there, he added.
