Prosecutors in Sweden announced on Monday that the murder of a woman at a political event last week would be looked at as a possible act of terrorism.

After a lady was fatally stabbed on the island of Gotland during a political festival conducted in advance of a September election, a man was detained.

Prosecutors said last week that he appeared to have acted alone and to have targeted her.

The Swedish Prosecution Authority said on Monday that the man was now suspected of “terrorist crime through murder”, and of preparing terrorist crime through the preparation of murder.

The authority added that there was no further suspect in the case.
