The Supreme Court Monday suggested that a former high court judge monitor the ongoing probe by the Uttar Pradesh police into the October 3 Lakhimpur Kheri incident in which eight people, including four farmers, were killed in violence during a farmers' protest, saying the investigation was not going the way it expected.

A bench headed by Chief Justice N V Ramana sought the response of the Uttar Pradesh government, represented by senior advocates Harish Salve and Garima Prasad, by Friday.
