The protestors are definitely calling for the release of Castillo. https://www.theweek.in/news/world/2023/01/10/peru-rejects-its-new-president-17-dead-in-violent-unrest.html Castillo tried to dissolve Congress to stop the investigation into his corruption and to block an impeachment. Castillo's VP - Boluarte is now the 6th Peruvian President in 5 years and has been on the job for 1 month. I assume she'll serve out the rest of his 5 year term and then be barred from running for re-election as Peru's constitution is currently written.
