A former Aum Shinrikyo fugitive was sentenced to life in prison Friday for his involvement in the 1995 nerve gas attack on the Tokyo subway system.

The court said Koichi Kitamura, 31, drove Aum member Kenichi Hirose, 35, to a Marunouchi Line station in Tokyo, where Hirose boarded a train and punctured two bags of liquid sarin, killing one person.

Prosecutors in May demanded that Kitamura be sentenced to life for conspiracy to commit murder.
