A Greater Manchester Police officer has been charged with causing serious injury by dangerous driving after a crash that left a teenage boy with a "life-changing injury".
He was struck by a police vehicle in December 2020, the Independent Office for Police Conduct (IOPC) said.
Sarah De Meulemeester, 25, based at Cheadle Heath police station, is due to appear before magistrates on Friday.
A second officer will face gross misconduct proceedings, the IOPC said.
That officer will face no criminal charges.
The IOPC has not disclosed any further details about the incident and did not confirm the location of the crash.
The BBC has contacted GMP for a response.
