A Kosovan-born gunman shot dead four people in a Finnish shopping mall and killed his ex-girlfriend in an apartment before killing himself in Finland's third shooting spree in as many years.
The man named as Ibrahim Shkupolli, 43, opened fire in the suburban Helsinki mall where his ex-partner reportedly worked.
He shot dead three men and a woman before fleeing the scene, detectives told a press conference.
The body of his former partner, whom he had been barred by a court from approaching, was discovered later in a house on the outskirts of the capital.
Police said they believed the incident was triggered by a domestic dispute.
Ambulances rushed to the scene in the suburb of Espoo after shooting erupted in the mall filled with New Year's Eve shoppers at around 8.20am Irish time.
Security services evacuated the shopping centre and then cordoned off the area while public transport services were rerouted.
After an extensive search of the mall proved fruitless, officers issued a photograph of Shkupolli and called on the public to help find him.
Media reports said the suspect opened fire with a 9mm handgun.
Eleven people were killed in September 2008 when a 22-year-old gunman burst into a school classroom, shooting dead eight female students and one male classmate as well as a male teacher, before turning the gun on himself.
An 18-year-old student also shot six students, a headmistress and a nurse before killing himself in a school in Jokela, north of Helsinki, in November 2007.
Both of the shooters had easily acquired a license for their handguns.
The gunman behind the 2008 rampage, Matti Juhani Saari, had been questioned by police just a day before the massacre about a video posted on YouTube showing him shooting his weapon at a firing range.
However, they deemed he was not enough of a threat to withdraw his gun licence.
