Made ampfetamin - was called 'Walter White'. Gang's secret photos

But through the 'Trojan Shield' operation the police were able to access the chats.

The suspected drugs criminals have communicated with one another via Anom and Sky ECC, two coded chat tools which they believed to be secure.

But police trackers were shadowing several of them even before the Swedish local police had access to the apps that had been broken into, and the chat conversations. According to the report from the preliminary investigation they have also used secret camera surveillance. In the enormous amount of material from preliminary investigations - 17,000 pages in all - there are a large number of photos from places in and around Kristianstad, Bromölla and Osby.

Several of those who have now been accused of particularly serious drugs offences can be seen in locations varying from petrol stations to storage areas. The cameras and trackers catch the suspects in different constellations and in the same places.

Among the places are 'drugs factories' in Osby and a stables in Blekinge where drugs are thought to have been hidden - stashed and kept - up in the attic or the hay-loft.

The persons under surveillance can be seen carrying big cans and large fans as well as cardboard boxes.

A deal is said to have been carried out at Ekohallen, and it is suspected that drugs have been stored at a kiosk in Kristianstad to which the person being detained has had access to.

An analysis is reported to have shown that amfetamin and caffeine were found on the fan inside the kiosk - a fan the suspect is believed to have bought at Hornbach.

The locations and what has been documented by the police range from a storage space at Österäng to rented storage premises on the west coast, the movements of the suspects outside CSK, on Stora Torg, in restaurants and laybys, to name but a few.

But surveillance was not confined to the physical world. Through the international Trojan Shield operation the police got a valuable boost. Previously completely closed chat-rooms were now wide open. The Sky service was put out of action, and Anom, which was a parallel alternative for people who thought they were speaking completely anonymously in closed virtual rooms, turned out to have tricked them.

The American FBI had designed the service, and could decode everything that was said in the Anom world.

In article after article investigators in the Kristianstad case could then read how the suspects call one another brother and talk about 'stashing', 'green', 'brown', 'cash' and 'para'.

They throw 'brother' around when they speak to one another, and discuss places for storage and where to deliver the goods, prices, quantities, interspersed with private details such as,'Going shopping with the family'.

The suspects have chat-names, and call themselves, for example, 'Hungrypretty', 'Cloudavoid', Tonguejungle', 'Makeelse' and less imaginative combinations of letters and numbers such as '4OGUAW' and 8FSMCQ'

They discuss deliveries, buyers, payments and 'how much they've got out of it'. At lunchtime one day in March 2021 the 41-year-old man from Kristianstad the police believe calls himself 'Tonguejungle' sends a picture of a man wearing protective clothing, gloves and a gas-mask.

This seems to be a clear reference to the fictitious character in the Netflix series 'Breaking Bad', which is about an ordinary chemistry teacher who goes through a metamorphosis and turns into a supercriminal maker of metamfetamin.

'Tonguejungle' even writes the name of the character in his chat message, 'Walter White'.
