The head of a Peruvian maximum security prison has been fired after video footage showed jubilant inmates drinking and dancing to live music with outside guests.
The November 10 party was to celebrate the birthday of Julio Rubio Roldan, who is serving time at the Miguel Castro Castro prison, according to America TV, which aired the footage on Sunday.
The video shows guests, including women and children, dancing and mingling with the inmates. Two cumbia bands equipped with electronic keyboards, drums and concert-sized speakers provide the live music.
Rubio dances, laughs, drinks whiskey, takes a phone call and accepts a birthday cake in the video. The crowd sings along when one of the bands plays "Happy Birthday".
Prison warden Jose Luis Mendoza and all of the guards on duty the day of the party were fired, said Julio Magan, head of Peru's prison system.
"These are corrupt, mafia-type personnel," Magan said on Monday. "This is a scandal that we are not going to allow."
The inmates involved in organising the party were also transferred to other prisons, Magan said.
A furious Prime Minister Juan Jimenez said he expected "more drastic sanctions", including criminal charges against the prison staff for allowing the party.
The Castro Castro prison was built in the 1980s to jail men sentenced for crimes like murder and rape. Rubio is on the 14th year of a 20-year prison sentence for kidnapping.
