"There were seven dead, including the pilot, co-pilot and five police officers," an official told AFP on condition of anonymity, adding that there were two survivors.
An earlier statement said the helicopter was carrying 11 passengers, but the prosecutor's office said two prisoners being transported in the government helicopter had already been delivered at the prison before the helicopter crashed.
The helicopter went down in the Veracruz state, some 250 kms east of Mexico City.The official said the crash was likely related to heavy fog in the area at the time of the crash
