"Recent spate of religious violence not isolated, but part of SAD-BJP's premeditated ploy to polarise the state ahead of elections. Despicable!," the former Chief Minister tweeted.
Torn pages of a religious book were found on the road near Jarag Chowk in Malerkotla on Friday night.
Immediately after the incident, Singh had expressed apprehension that the incident in Malerkotla was "conspiracy at the behest of the ruling party to disturb peace and destabilise Punjab" ahead of elections.
A year ago another religious book was desecrated in Faridkot leading to protests and firing which had left two persons dead.
