Spanish media reports that a 50-year-old municipal employee, who was robbed on Monday at Sant Jaume Square in central Barcelona, died on Wednesday.
A man, according to the newspaper El País 29 years old, was arrested at the robbery attack, when another person was easily injured. The Swedish Ministry of Foreign Affairs has confirmed that a man resident in Svealand has been arrested, but the Ministry of Foreign Affairs has no information on crime classification yet.
The Barcelona police are investigating possible links to two more murders that were carried out an hour before the robbery attack.
In one of the cases, a dead man was found in an apartment. The body, which was subjected to violence, was found after a fire department was alerted about a fire in the property. The circumstances led the police to launch a preliminary investigation into murder and arson.
Witnesses tell and video recordings show how a man leaves the property via the house's balconies, while smoke is emitted from the apartment where the dead man was later found.
Media reports claim that another dead person was found in a staircase in a residential building, about 600 meters from the first murder scene. The woman is believed to have been killed by a blow to the head, writes the Barcelona newspaper La Vanguardia.
The Policia de la Generalitat de Catalunya, often abbreviated as Mossos, first saw no connection between the crimes, but examined information that the arrested Swede may have links to the murders.
