German police have issued a sketch of a man they say could be linked to the murder of six Italian men in the northwestern city of Duisburg.
It is thought the killings were linked to a feud between two clans of the Calabrian mafia, the 'Ndrangheta.
The man being sought was one of two spotted near the scene of the shootings in the early hours of the morning.
Witnesses said the men fled the area at high speed. The sketch is of the driver of the car.
Investigators believe the Duisburg killings, which took place outside an Italian restaurant, were the latest chapter in a long-running feud between members of the crime syndicate.
Yesterday, Italian police searched houses and set up roadblocks around San Luca, the Calabrian town of 4,000 at the centre of the feud.
Italian secret services said in a report this month that the 'Ndrangheta was the most dangerous crime syndicate in Italy and one of the world's top drug trafficking cartels.
The German authorities have said the group established a presence in Germany some years ago.
