A 13-year-old boy was found dead on a river bank in Japan, having been stripped and stabbed repeatedly in the neck after weeks of bullying by an older gang.
Three teenagers, one aged 18 and two 17, have been arrested over the brutal killing of Ryota Uemura, who was found dead on February 20.
Friends of Uemurs told local media that he had fallen out with the older boys in January, and had been picked on since.
A makeshift shrine has been set up on the bank of the Tama River in Kawasaki, where Uemura's body was found, with flowers and basketballs left in his honour.
According to The Japan Times, the two 17-year-old suspects have laid blame for the killing at the feet of the older boy, who has reportedly now admitted guilt.
Prince William has visited the Forbidden City in Beijing as he continues his tour of China.
The Duke of Cambridge is the first senior member of the royal family to visit the country since the Queen in 1986.
During his visit he will be taken on a tour of the landmark, which has been the imperial palace complex of Chinese emperors for centuries.

Prince William has arrived in China for a high-profile trip that will see him highlight the illegal wildlife trade, visit some of the nation's most famous sites and meet a rescued elephant.
William's flight landed in Beijing after he had spent the day in Japan hearing the harrowing stories of survivors of the 2011 tsunami.
The Duke's four-day trip to China is the highest profile visit by a member of the Royal Family since the Queen's 1986 state visit and will be viewed as an attempt to improve diplomatic relations with the country.
On Monday the Duke will tour Beijing's Forbidden City before flying to Shanghai where he will launch the three-day Great Festival of Creativity at the city's Long Museum.
William - who has campaigned strongly to end the illegal trade in ivory and other endangered animal products - will travel to Yunnan province on Wednesday where 250 wild Asian elephants still roam free.
He will give a speech at a regional wildlife and conservation conference after seeing rescued elephants and learning how local communities live alongside the large animals.
The Duke of Cambridge has heard the harrowing stories of Japanese tsunami survivors during a visit to communities devastated by the disaster.
William toured a coastal area that saw thousands killed and tens of thousands made homeless when the huge wage struck in 2011 after being triggered by an earthquake.
In the city of Ishinomaki he met Hiroyuki Takeuchi, the now-retired former chief reporter at the Ishinomaki daily newspaper which produced handwritten editions when the disaster struck.
The Duke was shown a muddy mark 8ft up an outside wall of a museum which showed how high the tsunami had reached in this part of the city.
Next he went upstairs to meet Shinichi and Ryoko Endo, who lost their three children, Hana, Kana and Kanta, all of them under 12. Mr Endo, a carpenter, has been closely involved in the work of reconstruction. They gave William a wooden charm against fire made out of tsunami rubble, including oak, as the national tree of Britain.
The Duke of Cambridge is now on his way to China after a three day trip to Japan.
Earlier Prince William visited a Japanese coastal city to learn how communities coped with the devastating 2011 tsunami.
William toured Ishinomaki where more than 3,000 died and around 22,000 lost their homes when the city was deluged by a 28ft wave.
Prince William showed off his juggling skills during his visit to Japan - and proved he was rather good.
The Duke of Cambridge was also pelted with plastic balls as he played with children at an adventure playground in Motomiya City, the smallest town in Fukushima.
Japan's Prime Minister Shinzo Abe accompanied the Prince on his visit.
Since the Fukushima nuclear disaster in March 2011 - the largest since Chernobyl - many towns which were evacuated remain empty.
But the Prince visited a charity called Smile Kids, which aims to make the air and water around Fukushima safe.
Prince William was greeted by screaming crowds eager to get a glimpse of him as he visited a bookshop on the third day of his Japanese tour.
Crowds held up pictures of William and Kate, while one woman showed off a painting of the royal couple and Prince George.
And even their dogs got into the British spirit.
