Six members of the Nishiarai biker gang, aged between 15 and 18, were arrested in Tokyo’s Adachi Ward on Tuesday for violation of the Road Traffic Act. Members of the gang themselves called police, posing as residents to complain that bikers were roaring around the streets, disturbing the neighborhood, and requested that a patrol car be sent to the neighborhood.

After a police car arrived, the gang began playing what they call a “PC Game,” which comes from the initials of patrol ca’ and refers to the Japanese biker gang habit of taunting and baiting police cars.

Police eventually arrested the youths and learned that they were the same gang involved in an incident that occurred on Nov 12 last year at around 11:50 p.m. when bikers rode along streets, ignoring red lights for roughly one kilometer while being filmed by video cameras.

One gang member was quoted by police as saying, “We did it to feel the thrill of a police chase. I’ve done it two or three times before.”

London's luxury homes shrugged off a sluggish wider market in May as the flood of foreign cash into the capital's property scene shows little sign of ending, estate agent Knight Frank said today.

Traditional benchmarks such as the Nationwide and Halifax indices reveal a virtually stagnant UK housing market but top-end London property prices rose 1.4% over the month and are 8.3% ahead of last year.

Prices have risen 33% since their post-credit crunch low in March 2009 and are even 1.3% ahead of their previous peak in March 2008.

But the pound's tumble against the euro and the dollar in recent years still makes London property an attractive bet, according to head of residential research Liam Bailey.

"Foreign buyers are still buying at a discount when they factor in currency movements. The typical buyer purchasing a home using euros will find that prime London property is 16% cheaper than in September 2007 when the financial crisis started.

"Buyers using US dollars or a currency pegged to the greenback will benefit from a 17% discount over the same period," he said.

Asian buyers have snapped up 60% of new-build homes in Zone 1 in the past six months while European buyers are leading the chase for existing homes, the agent said.

French buyers account for 6% of the market, followed by Italy with 4.5% and Greeks with 3.1%.

Bailey added: "Price growth in the prime central London market shows little sign of slowing at the current time. Aside from a brief stumble last autumn, prices have been rising strongly since April 2009.
