Belgian police have arrested a man in connection with the murder of a teenager who was killed for his iPod.

Local lawmen have managed to trace one man, a 16-year old Polish youth. A second assailant is thought to have fled the country, a BBC report claims.

The murder sparked a wave of outrage in Belgium, with massed crowds marching in the nation's capital, Brussels.

Initial reports incorrectly claimed the killers were of North African origin.
