Eastern Uusimaa Police detained a 19-year-old man on Thursday morning in connection with the killing of a postal worker in Vantaa.
Police said the man turned himself in and confessed that he had carried out the violent crime.
The case concerns the murder of a postal worker in Vantaa's Myyrmäki district on 17 November.
According to police, the young female victim, who was delivering newspapers at the time of the attack, was subjected to 'brutal and cruel' violence. The young woman later died of her injuries in hospital.
"We will continue to investigate the case and are looking into this person's involvement and movements in the early hours that the violent attack took place," chief inspector Tero Tyynelä said in a press release.
Information seen by Yle suggested that the latest suspect in this case has not previously been a suspect or charged with a crime, at least according to Eastern Uusimaa District Court records.
The man does however have a history of financial difficulties, with Eastern Uusimaa's District Court having ordered the man to pay debts nine times this year.
Intitial suspect released
Police previously detained a 23-year-old man on suspicion of the murder, but later released him due to insufficient evidence.
"The man, who was previously a suspect, was released as police had no grounds to keep him in custody. We are still investigating the course of events of the night in relation to him," Tyynelä said.
Authorities continue to ask possible witnesses to come forward with any information that may be relevant to the case, particularly relating to sightings in Vantaa's Myyrmäki and Kaivoksela areas between 3 and 4am on 17 November.
