TAIPEI, Taiwan (AP) -- President Ma Ying-jeou has ordered Taiwan's police ministry to investigate what led a university student to stab four people to death on a crowded subway train in an attack that stunned the low-crime island nation.
The violence Wednesday at the start of rush hour in Taipei, a city of some 6 million people, was the first knife attack in the capital subway system's 18-year history. The attacker injured 21 other people before he was captured.
Ma said on his Facebook page that he told the Cabinet to "order the National Police Agency to do all it can to check into the situation behind this case."
The suspect, a central Taiwan university student, had said in an Internet commentary that he "wanted to do something big this year."
