Eighteen-year-old Abderrahman Mechkah has appeared before a court via a video link to admit a knife attack that left two women dead and eight other people wounded in the Finnish city of Turku.
Finland’s prime minister has described the stabbings as the country’s first terrorist attack.
However, the teenager denied murder and said there was no terrorist motive.
Three other suspects, all Moroccans, have been remanded in custody in connection with the 18 August attack.
Another man was released without charge.
Police said they were still searching for another suspect and trying to find out if the stabbings were planned from abroad.
The attack unfolded in the market square in Turku last Friday, a day after another Moroccan, Younes Abouyaaqoub, murdered 13 people on Barcelona’s Las Ramblas boulevard.
A man wielding a knife repeatedly stabbed one woman in the neck before running around, targeting other people, mainly women, nearby. Two of his victims died.
Within minutes Finnish police had shot Abderrahman Mechkah in the leg and arrested him. Two of those wounded by the attacker are still in intensive care in hospital.
