Some 80,000 people have publicly honoured teenager Joe Van Holsbeeck, who was stabbed to death by a youth attempting to steal his MP3 player. The 17-year-old’s brutal killing has sent shockwaves through Belgian society. Today’s silent march in Brussels brought many families onto the streets.At the request of Joe’s relatives, the occasion was strictly apolitical. Speculation his attackers were of North African appearance has sparked fears of a rise in racial tension. Those close to the slain teenager have made it clear that that is the last thing they want. Joe was attacked and killed at Brussels Central Train Station. There, in front of the main entrance, mourners left tributes. Police hope surveillance camera pictures will help them catch the culprits. A knife found near the scene of the crime is also being examined.
