Local media say the captain of a Hong Kong commuter ferry that collided with another boat in 2012, killing 39 people, has been found guilty of manslaughter.

The South China Morning Post and Radio Television Hong Kong say a jury Saturday also found Lai Sai-ming guilty of endangering the safety of others at sea.

The same jury found the captain of the other, smaller boat, Chow Chi-wai, innocent of manslaughter but guilty of endangering the safety of others at sea.

The two had blamed each other for Hong Kong's biggest maritime tragedy in decades, in which another 100 people were injured.

Fleets of ferries form the backbone of the southern Chinese city's transportation network, running frequently to outlying islands, the Chinese mainland and the gambling enclave of Macau.
