 While Ángelo and his brother-in-law was trying to get information as to what it was all about, a big husky man who was Tomás Briones (also one of the nineteen martyrs), one of the officers, persuaded them to get inside the chapel, and once inside they were blind-folded with the others without their expressed consent.They were made to swear allegiance to the creed of the Katipunan by following after a dictated oath, after which the arm was pricked with a pointed blade until it bled.Taking off the blindfold, they were made to sign their names on a scroll with their blood to signify that they are now members of the KKK.
