On the evening of 8 May he stabbed a policeman in the Lambrate train station . Today, almost a month after the attack, the Milan Prosecutor's Office closed the investigation, in view of the request for trial also for the accusation of "attack on transport safety", against Hassine Hamis , a 37-year-old irregular Moroccan . That evening, the victim of the ferocious attack was Police Deputy Inspector Christian Di Martino , who managed to save himself thanks to the intervention of his colleagues and delicate surgical operations and was then discharged in recent days.

Hamis, defended by the lawyer Alfredo Quattrocchi Rosmi Gervasoni, is therefore headed for trial on charges, as stated in the notice of conclusion of the investigation, of attempted murder , resistance to a public official , injuries to two other agents , port of the knife (30 centimeters long with a 20 centimeter blade) and false attestations on his identity , because during the various checks by the police in recent years he presented himself with at least 22 different aliases. The man, as stated in the document with a charge against him, would have hit a woman in the head on the same day, throwing stones at her "from the railway bed". The deed now also includes a charge of injuries to a woman who that evening was hit on the head by "stones" taken "from the railway bed" and which the 37-year-old threw from above onto a street adjacent to the station. And also that of an "attack on transport safety", because he also threw those stones at "moving trains". He is also accused of damaging a regional train which was hit on that occasion.

According to the public prosecutor, Hamis "wanted to kill" and was saved only thanks to the intervention of the other officers present, who managed to disarm him, and the "extreme skill of the healthcare personnel" of the Niguarda hospital. After his arrest, before the investigating judge, the 37-year-old supported his version according to which he had not seen that they were policemen and that they had not had the intent to do harm. Furthermore, in the interrogation, he said that he had been taking Rivotril (benzodiazepine) since 2003.
