The Project's Waleed Aly has launched a scathing attack on Prime Minister Malcolm Turnbull, writing off his recent comments about Sudanese gangs as a last-ditch votes grab before Super Saturday byelections next weekend.

In an eight-minute editorial package written with The Project producer Tom Whitty, Aly on Thursday presented a number of statistics that placed question marks on recent claims by several politicians that violent African gangs were "wreaking havoc" in Victoria.

"This week the Prime Minister said something interesting," Aly started, cutting to a video of Turnbull in a 3AW interview earlier this week.

"There is real concern about Sudanese gangs," Turnbull says in the video. "You have to be walking around with your hands over your ears in Melbourne not to hear it."
