A car which was being chased by police went through the central reservation of the A1M at Peterborough and closed both carriageways on Wednesday July 20.
The crash involving five cars, including two police cars, took place between Norman Cross and Haddon. All eight lanes were closed northbound and southbound.
Both carriageways reopened at around 6am after Highways England repaired the crash barrier.
A police spokesman said: “Police can confirm a collision involving multiple vehicles has occurred on the northbound carriageway on the A1M.
“Two police cars were pursuing a vehicle which was suspected of being stolen and had failed to stop.
“The collision happened near the Norman Cross junction at 4.30pm and involved five vehicles.
“The vehicles were two police cars, the alleged stolen vehicle and two members of the public.
“The injuries are not thought to be serious or life changing.
“A 22-year-old man has been arrested and is en-route to Thorpe Wood Police Station.
“The road is likely to be closed for at least another three hours.”
Ambulance crews were called at 4.34pm to the northbound carriageway near junction 16. An ambulance crew is on scene treating a male patient.
Delays built up on the A15 and were made worse by a crash on Fletton Parkway at around 7pm which shut two lanes of the westbound carriageway but has now been cleared. UPDATE: Three police officers injured and suspect in hospital after police chase ends in crash on A1M at Peterborough
