The police received a number of reports of a car driving on the E6 just before 10.30 pm on Wednesday night, operations manager Kristian Loraas informs NRK.

At least one person has died in the accident, police wrote Twitter.
– We are working on notifying relatives at the moment, but we do not have a 100 percent secure ID on the deceased yet.
The road is completely closed in a southerly direction, and will be closed for a good while during the night.
The fire brigade in Lillestrøm has responded to the accident.
