A man who died in a car fire on a Lincolnshire motorway after being followed by police had been arrested the day before, it has emerged.
The man died when the car he was driving caught fire on the M180 near Scunthorpe while it was being pursued by Lincolnshire Police last Wednesday.
The Independent Police Complaints Commission (IPCC) is investigating the force's contact with the man.
It said he was arrested and bailed by officers the day before his death.
The IPCC said the man, who has not been named, was taken into custody after the vehicle he was in was recognised by an automatic number plate recognition system on 12 October.
A spokesman would not reveal why the man was arrested but said he was released on bail later that day.
The IPCC said officers then followed the man on 13 October after the car he was driving was again recognised by the system.
The pursuit crossed over into the Humberside Police force area and continued on to the M180.
An IPCC spokesman said: "During the pursuit the car came to a stop on the hard shoulder of the highway and when officers approached the car it was on fire.
"Unfortunately the sole occupant of the vehicle died.
"Lincolnshire Police referred the incident to the IPCC on 13 October and following an assessment a decision has been taken to carry out an independent investigation."
IPCC commissioner Amerdeep Somal said: "Given the prior contact with police, it is right that we carry out an independent investigation to ensure all correct policies and procedures were followed when this person was released on bail."
