HELSINKI (Reuters) - Finnish police on Friday released another of the men suspected of involvement in fatal stabbings in the city of Turku on Aug. 18, leaving just one suspect in custody.

Officers arrested seven people after the attack and have now released six of them without charge.

Two women died and eight people were wounded in the mid-August knife attack, which police are investigating as Finland’s first terrorism-related assault.

The main suspect, who is in pre-trial detention pending an investigation, has been named as Abderrahman Bouanane, a 22-year-old Moroccan asylum seeker. He told a court last week he was responsible for the attack but denied his motive was terrorism.
