Police are treating the “mindless” gun attack on officers in west Belfast on Thursday, 26 November as attempted murder.
Up to 8 shots were fired, possibly from a heavy calibre machine gun, at the unmarked car which was parked in Rossnareen Avenue at 6.50pm.
Several rounds hit the passenger side of the car but neither of the two officers was physically injured.
Detectives believe the attackers made off in a BMW car that had been waiting nearby at Tullagh Park.
The car, which was fitted with a false Republic of Ireland registration plate, was later found abandoned and on fire at Cluain Mor Drive in the Beechmount area.
It has now been seized for forensic examination.
Belfast Commander Chief Superintendent Nigel Grimshaw said: “This was a mindless and reckless attempt to kill police officers who were carrying out routine duties as part of an investigation into recent serious crime in the area.
“Thankfully it failed.
“The two officers were badly shaken but not physically injured.
“Detectives have begun an investigation into this attempted murder and I would appeal to anyone in the community with information to contact police on 101.
“Or, if someone would prefer to provide information without giving their details they can contact the independent charity Crimestoppers and speak to them anonymously on 0800 555 111.
“This will not deter these officers or their colleagues from providing a much needed and increasingly valued police service in west Belfast. We remain determined to work with communities to keep people safe. We are equally determined to provide the fullest protection to our officers when they are on duty.
“We will review our procedures in light of this gun attack but we will not be deterred from providing a comprehensive and community based policing service.
“Those who believe that trying to kill our officers will achieve anything are deluded.”
