Now, the Independent Office for Police Conduct (IOPC) has confirmed it is looking into GMP's response to the incident.
It says a police vehicle is believed to have been 'one of several' which hit the body on the M67 in Tameside earlier today.

The IOPC is assessing the incident before considering whether to launch a further investigation.
A spokesperson for the IOPC said: "We attended an incident on the M67, where a man was sadly found dead this morning.
"We were made aware by GMP due to the fact a police vehicle was one of several believed to have been involved in a collision with the man.
"Investigators attended the scene and post-incident procedures and we have requested further information from the force which we will assess to determine what further action may be required."
GMP confirmed a body had been found on the motorway earlier on Saturday.
Police remained at the scene throughout the day and enquiries into the incident are ongoing.
A GMP spokesperson said: "Police were called around 7am today (December 18) to a report of a body being found on the M67 close to junction two.
"Emergency services attended and a man has sadly been pronounced dead at the scene.
"The motorway is currently closed and officers are keeping an open mind about the circumstances surrounding the man's death whilst enquiries continue."
The eastbound side of the M67 was closed for over 12 hours between Denton Island and Hyde from 7.30am yesterday, while the westbound carriageway remain closed for a number of hours.
