The 23 year-old Moroccan national accused of carrying out the Turku stabbings last summer, Abderrahman Bouanane, was escorted out of the courtroom on Wednesday after an angry outburst at a witness' testimony.
The witness, who'd suffered injuries after chasing Bouanane during the attack, called the attacker's actions cowardly, prompting the defendant to stand up and scream, according to Finnish news agency STT.
After requests from court officials for the defendant to calm down were not followed, guards then escorted him out of the courtroom for the remainder of Wednesday's proceedings which were closed shortly afterwards.
Bouanane faces charges of two counts of murder with terrorist intent and eight counts of attempted murder with terrorist intent in the attack that claimed the lives of two women and injured eight others on August 18, 2017.
Bouanane's trial is planned to be held in its entirety at the auditorium of Turku prison, in south west Finland. Members of the public and media are not permitted in the courtroom for the duration of the trial, but instead permitted to view proceedings via live video link.
The trial, which has set aside two days for questioning of the defendant, is expected to wrap up in the middle of May, when a sentence hearings is anticipated to commence. The criminal trial is scheduled to resume next Monday.
