A 27-year-old man was hit in the face with a hammer as two hijackers stole his car in west Belfast.
The incident happened at around 5pm on Norglen Parade yesterday. The gold coloured Peugeot 206 was later found on fire on Rossnareen Avenue.
Sinn Fein MP for the area Paul Maskey said: "There needs to be unity across the board to deal with this and the community in west Belfast and across the city demand that they are protected from these thugs.
"The PSNI need to do their job and the judicial system also need to step up to the mark."
Chief Superintendent Alan McCrum said: "Police are working tirelessly and very robustly to make the city a safer place.
"We continue to take car hijacking very seriously. We continue to make very many arrests and I'm confident that we will make more arrests as the investigations proceed.
"I want to reassure the community that no stone will be left unturned in doing everything possible to eradicate this scourge."
There have now been 16 carjackings in the Greater Belfast area since the beginning of the year and seven attempted hijackings.
