A court in the central Russian city of Perm has sentenced a prominent nightclub owner to nine years and 10 months in jail over a deadly fire in December 2009.
Anatoly Zak and four former associates in his Khromaya Loshad (Lame Horse) nightclub were found guilty of manslaughter on April 30.
The four were sentenced to prison terms of between four and six years.
Two former officials from the local fire-safety directorate were found guilty of negligence and sentenced to four and five years in jail.
The fire at the nightclub in Perm killed 156 people and injured dozens of others.
Investigators say the blaze was caused by fireworks used in the nightclub that set the ceiling alight.
The Perm provincial government resigned and several officials in the regional fire-safety directorate were dismissed after the incident.
