Moroccan national Abderrahman Bouanane, who was sentenced to life imprisonment for the Turku terrorist attack in 2017, will face three charges of assaulting guards in Turku prison.
The charges were filed with the District Court of Southwest Finland earlier this month, as Bouanane is suspected of violently resisting a public official on 13, 15 and 31 October 2020.
According to Yle's information, the convicted killer is understood to have allegedly kicked one guard and bit another on the finger.
No date for the hearing has yet been set for the proceedings. Bouanane has since been transferred from Turku Prison to another facility.
On August 18, 2017, Bouanane stabbed two people to death and injured eight others in the centre of Turku, in what became Finland's first legally-defined terror attack. The attack began at about 4.02pm and lasted roughly three minutes, before Bouanane was shot in the leg and apprehended by police.
In August 2018, the District Court of Southwest Finland found him guilty of two counts of murder with terrorist intent and eight counts of attempted murder with terrorist intent.
