A packed house of nearly 50,000 were at Strawberry Arena to see one of the most heated rivalries in northern Europe, but the majority of the fans went home disappointed as Djurgarden came away with the win.
The visitors went in front just 10 minutes in when a searching ball found Patric Aslund at the byline, and his cutback was deflected into the path of Hampus Findell, who guided it into the bottom corner.
Djugarden were two up just six minutes later, when a deep Bo Hegland corner was met by a towering Miro Tenho header at the back post, which found its way past the goalkeeper and defenders on the line despite the tight angle.
Midway through the first half, AIK were right back in it, when Zadok Yohanna skipped away from his marker and cut the ball back to give Kevin Filling the easiest of finishes. Then, they thought they were level in the 37th minute when Axel Kouame's shot hit the post and Filling tucked away the rebound, only to be denied by an offside flag, despite replays showing Filling was clearly onside.
After that bitter blow, Blaranderna delivered another in first-half added time, as Hegland delivered another wonderful set piece, and this time his floated free-kick was headed home by Mikael Marques.
But Gnaget wouldn't lie down and made it a one-goal game again approaching the midpoint in the second half - this time it was Aron Csongvai's delivery from a corner that was powered in by Dino Besirovic.
However, it was perhaps fitting that Hegland would have the final say four minutes from time, running onto a Kristian Lien through ball and firing low across Kristoffer Nordfeldt to seal Djurgarden's second win in a row that keeps them in fourth. AIK are ninth following one point from their last four games.
There were five goals in a frantic first half in Gothenburg and three of them went the way of Hacken who held on to beat Malmo - a first win in four for Getingarna who remain unbeaten, while MFF have now lost three of their last four.
It took less than four minutes for Hacken to carve open the away defence - Adrian Svanback played Gustav Lindgren through and he finished in style. 16 minutes later it was 2-0, Lindgren was the target of Amor Layouni's cross, but the final touch came off Malmo's Jens Stryger Larsen.
The visitors made a quick response and were back in it four minutes later, when Otto Rosengren played a corner low to the edge of the area for Busanello to hit first time, and his effort found its way into the net via a big deflection.
With eight minutes of the first half to play, Adam Lundqvist fired over a low centre which Lindgren did not make clean contact with, but he just about managed to force over the line for his fifth of the season. This time, MFF needed just two minutes to reply, as Sead Haksabanovic's free-kick was met at the near post by Erik Botheim, who flicked it on to see it nestle in the far corner.
In the second half, Lindgren wasted a good chance for his hat-trick before Filip Helander and Silas Andersen both came very close to putting the game to bed. In added time, Stefano Vecchia looked certain to equalise, only to plant his shot straight at Andreas Linde.
Hacken are in fifth, behind Djurgarden only on goal difference, while Malmo are three points adrift in seventh place.
Halmstad parted company with Johan Lindholm after just two points in their opening six matches, and life under new head coach Stuart Baxter - returning to the club after a first spell in charge from 1988-91 - didn't get any better, as they lost to Kalmar, who climb out of the bottom three.
The home side broke the deadlock early in the second half when a Charlie Rosenqvist cross to the back post was cushioned in on the volley by Charles Sagoe Jr, and Kalmar but real daylight between the teams just eight minutes later when Rony Jansson's through pass found Marius Soderback, and he tapped it back for Anthony Olusanya to guide into the bottom corner.
After a slow start, it's two wins in three now for Kalmar, while HBK have now lost three in succession and remain at the foot of the table.
