Four prisoners who took three prison officers hostage

Four prisoners who took three prison officers hostage at Picassent jail, near Valencia, yesterday evening have been split up and transferred to different jails. The crisis began at around 6pm yesterday evening when four prisoners from the high-security wing took three officers hostage, apparently using one of their fellow prisoners as a bargaining chip.
Two of the three officers, both in their twenties, were released shortly after midnight and following all-night negotiations, the third man was set free shortly after 6am this morning.
