    HONG KONG, Oct 2 (Reuters) - Hong Kong police arrested six

    crew on Tuesday after a ferry and a company boat carrying more

    than 120 staff and family celebrating the mid-autumn festival

    collided, killing 37 people as the boat sank.

    The boat, belonging to Hongkong Electric Co, controlled by

    billionaire Li Ka-shing, was taking passengers to watch

    fireworks in the city's Victoria Harbour on Monday when the two

    vessels collided near the picturesque outlying island of Lamma.

    Five children were among the dead. More than 100 people were

    taken to hospital, with nine suffering serious injuries or in

    critical condition, the government said in a statement.

    "We suspect that somebody did not fulfil their

    responsibility, that's why we made the arrests," Police

    Commissioner Andy Tsang said. "We do not rule out the

    possibility that further arrests will be made."

    The arrests involved crew of both vessels.

    The collision sparked a major rescue involving dive teams,

    helicopters and boats that saw scores plucked from the sea. A

    large crane on a barge was connected to the stricken boat.

    "Within 10 minutes, the ship had sunk. We had to wait at

    least 20 minutes before we were rescued," said one male

    survivor, wrapped in a blanket.

    Survivors said people had to break windows to swim to the

    surface. "We thought we were going to die. Everyone was trapped

    inside," said a middle-aged woman.

    The fireworks marked the mid-autumn festival, when the moon

    is full, and China's National Day. Hong Kong returned to Chinese

    from British rule in 1997.

    Hongkong Electric, a unit of Power Assets Holdings

    which is controlled by Asia's richest man Li, said the boat had

    capacity to hold up to 200 people.

    The tragedy was the worst to hit Hong Kong since 1996 when

    more than 40 people died in a fire in a commercial building.

    "OUR CAPTAIN IS NOT WELL"

    The ferry, owned by Hong Kong and Kowloon Ferry Holdings,

    suffered a badly damaged bow in the collision but made it safely

    to the pier on Lamma, an island popular with tourists and

    expatriates about a half-hour away from downtown Hong Kong.

    Several of its roughly 100 passengers and crew were injured.

    "After the accident, it was all chaos and people were

    crying. Then water began seeping in and the vessel began to tilt

    to one side and people were all told to stand on the other side

    and everyone started putting on life jackets," a passenger said.

    Hong Kong is home to one of the world's busiest shipping

    lanes, but serious accidents are rare. The city is known for its

    high-quality public services and advanced infrastructure.

    A spokeswoman for Hong Kong and Kowloon Ferry said the

    company was trying to assess what happened.

    "Our captain is not well and we have not been able to talk

    to him so far," the spokeswoman told local television.

    A Hong Kong Fire Services official said the search was

    hampered by the vessel being partly sunken, poor visibility and

    too much clutter. The search for survivors was continuing on

    Tuesday.

    Teams of men in white coats, green rubber gloves and yellow

    helmets carried corpses off a police launch in body bags.

    At one of the city's public mortuaries, around 50 grieving

    relatives gathered, some crying, while others were called in to

    identify the dead.

    Hong Kong leader Leung Chun-ying visited survivors and

    pledged a thorough investigation. He declared three days of

    mourning starting on Thursday.

    Thousands of Hong Kong residents live on outlying islands

    such as Lamma, which lies about three km (two miles) southwest

    of Hong Kong Island.
