Blood and drama this morning in Sassari, in an ERSU building that houses students between Via Rosello and Via Lamarmora.

According to initial reports , a young resident of the facility first stabbed a security guard assigned to the building's security detail, then jumped into the air. The exact circumstances of the incident are still under investigation.

The boy was rescued by 118 emergency workers: his condition is serious. The security guard's condition is less worrying.

The incident is being investigated by the Police Headquarters' Flying Squad: Officer Michele Mecca and his Flying Squad colleague Virginia Martinazzi are on site.

Mayor Giuseppe Mascia was also present, along with the local police.

The chronicle of the drama

"We saw him jump to his feet." Witnesses on Via al Rosello in Sassari described the stabbing and attempted suicide that occurred between 9:20 and 9:30 a.m. "He had first thrown a laptop, and the doorman of the Ersu building intervened," they reported. Then the 23-year-old Moroccan, who had been occupying a room on Via La Marmora for a few days, along with other students, allegedly stabbed the 33-year-old doorman.

It's currently unclear what triggered the violence. " We heard screams for help, and then the boy appeared on the roof." According to initial reconstructions, he climbed up from the laundry room, exiting through the skylight, and walked along the roof. "He threw his slippers down. I yelled at him to stop." Then came the four-story fall, the impact, and the very serious injuries. Emergency services took the young man to the emergency room at Santissima Annunziata, in critical condition.

The caretaker, on the other hand, had several stab wounds, including on his head, but fortunately he's not in critical condition. "I've only seen this boy twice," a student said, "when he was hitting the caretaker and then falling to the ground."
