Sinn Fein has accused “cowardly” dissident republicans of endangering police lives after a PSNI vehicle was hit by gunfire in west Belfast.
The attempt to kill an officer on Friday caused minor damage to the vehicle.
The incident happened in the Glen Road area at around 4am last Friday.
It is understood that details only emerged last night as officers were following a number of lines of inquiry to establish the exact details of the incident.
Paul Maskey, Sinn Fein’s West Belfast MP, said: “This type of pointless activity will achieve nothing and only puts in danger the lives of both the police and local residents.
“This community deserves an accountable and proper police service and micro groups involved in this activity will not stop us from making sure that is delivered.”
Chief Superintendent George Clarke said it was completely unacceptable that officers carrying out their professional duties on behalf of the community should be subjected to a potentially murderous attack.
“This was a reckless and cowardly attempt to kill a police officer which also put the lives of the local community in danger and it is fortunate that no-one was injured or worse,” he added.
“These people who carried out such a senseless attack show a total disregard for the safety of those living in the area.
“They will not stop us from delivering a protective service and we will put in place any measure necessary to take a robust stance against those who are determined to disrupt and attack their own communities.”
The murder bid came hours after different dissident republican factions announced that they had joined forces.
There had been fears the group would attempt to kill a PSNI officer to announce its arrival.
The police appealed for anyone who witnessed suspicious activity in the area to contact them.
