A 40-year-old rightwinger was arrested Wednesday morning after he hurled a Molotov cocktail at a Bank of China branch here, police said.

Yoshinori Kawabe, of Yokosuka, Kanagawa Prefecture, was quoted by police as saying that he attacked the bank building because he was angry about the anti-Japan demonstrations in China.

No one was injured in the 6:20 a.m. attack, which scorched a wall and sidewalk outside the branch.

Police have been guarding the bank branch since April 10, when a suspected rightwinger fired a round, possibly from an air gun, at the entrance, cracking a glass door.
