Finnish police say they have arrested two more suspects in connection with last week's stabbings that killed two people and wounded eight in a knife rampage in the southwestern city of Turku.

Turku police said Wednesday they arrested two men on suspicion "of preparation of an offense to be committed with terrorist intent."

On Tuesday, a regional court ordered that an 18-year-old Moroccan asylum-seeker be detained on suspicion of terrorist crimes, including two counts of murder and eight counts of attempted murder.

Three alleged accomplices also were ordered to be held on suspicion they helped plan the attack.

The main suspect, who has acknowledged the stabbings but denies murder, was named as Abderrahman Mechkah although police said they believe he is using a false identity.
