Police in Japan have arrested four Vietnamese men for allegedly snatching a bag of a Vietnamese woman and stabbing a man who tried to stop the crime.
Nippon TV reported that they robbed the bag containing 500,000 yen (US$4,434) on a street in a small town north of Tokyo on Tuesday.
A Vietnamese man tried to chase after them, only to be stabbed several times and severely injured.
Police caught three of them the next day.
One of the suspects, 21, has admitted to robbing the bag while the other two, 22 and 23, said they did nothing.
Another Vietnamese, 26, gave himself up on Thursday, saying he was the one stabbing the man.
They are all under investigation for robbery and attempted murder, the report said.
