Authorities in Finland have received a Spanish request to arrest separatist Catalan leader Carles Puigdemont.
The arrest warrant was issued on Friday, a day after his arrival there.
The ex-leader has been living in self-imposed exile in Belgium since last October’s banned referendum that backed Catalonia’s unilateral secession bid.
Tensions in the region are very high and separatist leaders have abandoned plans to name a new president following the arrest of the latest candidate.
Crowds of protesters clashed with police in Catalonia on Friday night after Spain’s Supreme Court ruled 25 Catalan leaders should be tried for rebellion, embezzlement or disobeying the state.
Convictions could result in up to 30 years in prison.
One of those taken into custody was Jordi Turull, who was to be the subject of a vote in the Catalan parliament on Saturday for regional president.
