These crimes become available after completing the Keeping the Peace mission. Thug Crimes can turn into a hostage situation which will fail if the victim is not saved. They are also the subject of some Just the Facts episodes—namely the episodes "Breaking In" (prompted by failing a Break-In crime), "A Loop" (prompted by failing to capture the suspects in a Drug Deal crime), and "Blame the Internet" (prompted by failing to stop the car in a Stolen Vehicle crime). In all of these episodes, J. Jonah Jameson will criticize Spider-Man for his failures.
These crimes are split up in groups of three, as certain crimes become available by progressing through the story. Demon Ambush, Demon Armored Car, and Demon Shootout are unlocked upon completing the Financial Shock mission. Demon Bomb Threat, Demon Hostages, and Demon Truck Bomb are unlocked upon completing the And the Award Goes to... mission. Checkpoint Assault, Demon v Sable Roof, and Demons vs Sable are available upon completing the Dual Purpose mission. Upon completing the Out of the Frying Pan... mission, the Demon Crimes will require the defeat of all Sable agents involved.
These crimes become available after completing the Jury Rigging mission in the "Turf Wars" DLC, and involve crimes committed by Hammerhead's thugs. More Hammerhead Crimes are added in the "Silver Lining" DLC, available to players after completing the mission Rio Bravo. Like Maggia Crimes, they have no bonus objectives.
