An Essex County man is dead after a brief police pursuit, and Ontario's Special Investigations Unit is investigating.

The OPP tried to stop a driver on Manning Road around 12:25 a.m. Thursday.

Police say the driver fled.

A short distance later, according to police, the vehicle ran off the road into a ditch.

The male driver was ejected from the vehicle and pronounced dead in hospital.

The SIU is now on the scene leading the investigation.

Three investigators, three forensic investigators and a collision reconstructionist are working the case.

Manning will remain closed between County Roads 46 and 42 for several hours.
