Prisoners Release Warders in Spanish Jail

`It hasn`t been necessary to use force. It`s been a long process of negotiation,` said Gallizo.

Prisoners have released three warders taken hostage in a jail in Spain's eastern city of Valencia, a senior official said on Wednesday.

Four prisoners in the city's Picassent jail had held the officers since Tuesday evening and asked for drugs and guarantees they would be released and not harmed, said Penitentiary Institutions General Director Mercedes Gallizo.

"It hasn't been necessary to use force. It's been a long process of negotiation," said Gallizo.

The prisoners are being transferred to other jails and face punishment for taking the warders hostage, she said.
