Sixty-four people were arrested nationwide for World Cup-related crimes prior to last weekend, the National Police Agency said Monday.

Japanese made up the majority of the alleged wrongdoers, accounting for 40 of the arrests that were made as of Friday. Twelve Britons, three Irish nationals, two Americans and two Argentines were also arrested.

Twenty-four of the arrests were over ticket scalping, 11 were for obstruction of police and five were for trespassing into stadiums.

Other arrests were for causing injuries, assaulting others or for public indecency, police said.

By location, 18 of the arrests were in Hokkaido, 12 in Tokyo and 10 in Osaka Prefecture.

Meanwhile, 15 Britons and an Irish national have been refused entry into Japan at Narita and Kansai airports after being identified as known hooligans.

Two Britons and a German who had already entered the country had their permission to stay revoked after later being identified as hooligans.

The World Cup runs until June 30.
