NXT General Manager William Regal continues his growing investigation into who attacked Aleister Black. As reported, Black was mysteriously assaulted just days before TakeOver: Brooklyn IV, prompting widespread speculation on a possible suspect. In the weeks since, Regal has interviewed a slew of NXT Superstars, including The Forgotten Sons, Heavy Machinery, Nikki Cross, Lars Sullivan, Kairi Sane and Johnny Gargano, who was scheduled to face off with Black, along with Tommaso Ciampa, at TakeOver. Last week, Ciampa went on record and denied any involvement in the attack. As the investigation continues, this week should proffer more updates.
