Union Minister Ajay Mishra's son Ashish Mishra, who is accused of running over farmers in Uttar Pradesh and was arrested on Saturday after being questioned for over 12 hours in Lakhimpur Kheri was sent to police custody for three days on Monday.
The police, after arresting Mr Mishra, said he had been giving "evasive answers" and not cooperating.
The UP police had filed a case of murder against Ashish Mishra but had not arrested him so far. Though the Union Minister admits the SUV that ran over farmers belongs to him, he maintains his son was not in it.
Eight people, including four farmers, died in the UP district last week after a car ran over a group of demonstrators protesting against the visit by junior Home Minister Ajay Mishra and UP's Deputy Chief Minister Keshav Prasad Maurya.
The farmer said that the incident was a "pre-planned conspiracy". They demanded that Union Minister Ajay Mishra should also be removed from the government as he started this conspiracy and is also protecting the culprits in the case.
