Europe arrests over mafia killing

Six Italian men from the Calabrian Mafia, the 'Ndrangheta, were shot dead outside a pizza restaurant in August.

Two of the arrests were made in Germany's North-Rhine Westphalia region and two in Calabria, southern Italy. Police are looking for a fifth suspect.

The authorities believe the killings were part of a long-running vendetta.

Clan feud

Two of the suspects were arrested in the small Italian town of San Luca, the focal point of a bitter feud between rival clans among the 'Ndrangheta.

The town has been blighted by mafia killings for more than a decade.

The other two suspects were arrested in North-Rhine Westphalia, where Duisberg is situated, after a tip-off from Italian police.

The four are not believed to have been directly involved in the murders, Italian media say.

The murders took place on 15 August after a birthday party celebration.

The 'Ndrangheta, which is notorious for vendettas, is believed by police to control cocaine trafficking in many parts of Europe.

The clan feud in San Luca, a town of about 4,500 at the southern tip of Italy, dates back to an egg-throwing incident in 1991.

A fight broke out which left two young men dead and another two injured.
