After Riina was captured in January 1993, numerous terror attacks were ordered as warning to its members to not turn state's witness, but also in response for the overruling of the Article 41-bis prison regime. On 14 May 1993, television host Maurizio Costanzo, who had expressed delight at the arrest of Riina, was almost killed by a bomb as he drove down a Rome street; 23 people were injured. The explosion was part of a series. Less than a fortnight later, on 27 May, a bomb under the Florence Torre dei Pulci killed five people: Fabrizio Nencini and his wife Angelamaria; their daughters, nine-year-old Nadia and two-month-old Caterina; and Dario Capolicchio, aged 20. Thirty-three people were injured. Attacks on art galleries and churches left ten dead and many injured, causing outrage among Italians. Some investigators believed that most of those who carried out murders for Cosa Nostra answered solely to Leoluca Bagarella, and that consequently Bagarella actually wielded more power than Bernardo Provenzano, who was Riina's formal successor. Provenzano reportedly protested about the terroristic attacks, but Bagarella responded sarcastically, telling Provenzano to wear a sign saying "I don't have anything to do with the massacres".
