Batman hates calling the league for back-up. Gotham is his city, he understands it. The other leaguers are too loud, too conspicuous, too... brightly dressed for Gotham. Especially a certain over grown boy scout who tends to knock over buildings when he fights. Unfortunately, he was going to need help from the primary-colored wrecking crew he calls his teammates to solve this case, so he took a calming breath and began the briefing.
"Thank you all for coming. Two weeks ago Gotham PD began receiving reports of attacks-"
"Wait, Gotham?" Green lantern interrupted. "As in 'stay the hell out of my city' Gotham? You want help in Gotham?" Batman gave the Glowing Green Target a bat-glare that would scare the paint off the walls until Hal began to squirm and mumbled "Not that you need help or anything..."
"As I was saying, two weeks ago Gothem PD began receiving reports of attacks, 15 so far. The victims are different ages, races, and income levels. The only things they have in common is that they are all male and many of them have records of violent crimes against women. In fact, five of the victims' DNA matched samples from unsolved rape cases."
"So what? It's an over zealous new hero who doesn't know Gotham is your town. Go do your 'I'm Batman' bit and chase him off." Aquaman said, annoyed at being bothered with this petty nonsense.
"Whoever is doing this is no hero. The attacks were rapes. Someone is raping the rapists in Gotham."
"Eeewww..." Flash said with a cringe.
"That is sick." Hal exclaimed.
"Disgusting." Agreed Wonder Woman.
"How would you- WHY would you... ick" Cyborg couldn't bring himself to finish the question.
"Ok, so not just a misguided rookie then. Did anyone get a good look at the guy?" Asked Superman.
"Yes, several of them did. Each man identified the attacker as himself. Not that he did it to himself, but that another "him" attacked and raped him. My first thought was a shape shifter, but there is also a total lack of physical evidence. No bruises, no trauma, no... DNA. No indication these men were physically attacked. I believe the attacks are telepathic, and the culprit is using his telepathy to track me."
