BERLIN, Germany (Reuters) -- German police have issued a sketch of a man thought to be linked to the gangland-style killing of six Italian men this week, attributed to a mafia clan feud, in the northwestern city of Duisburg.
The man in the sketch was one of two spotted near the restaurant where the killings took place.
Police found the victims with gunshot wounds to the head outside an Italian restaurant near the city's train station in the early hours of Wednesday morning.
The man in the sketch was one of two spotted near the restaurant, Duisburg police said. Witnesses said the men fled the area at high speed in a large, dark-coloured car.
A local mechanic told Friday's edition of Bild newspaper he had stopped on his way home to drop off a colleague and saw two men next to the restaurant shortly before the shootings.
"They were dressed in dark clothing and one was looking through the window into the pizzeria," the mechanic, named as Michael M., told the newspaper.
"When we stopped, they moved away a touch into the shadow of the building," he said. "I only learned what had happened there the next morning and an icy shiver went down my spine."
The sketch of the car's driver shows a dark-haired man, clean-shaven apart from long sideburns and with a dark mole beneath his right eye.
The man has a thin frame and stands at 180-185 centimetres or just over six feet tall.
Investigators believe the killings were the latest chapter in a long-running feud between two clans in Italy's region of Calabria, home to the 'Ndrangheta crime syndicate.
On Thursday, 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 world's top drug trafficking cartels.
The German authorities have said the group established a presence in Germany some years ago. Duisburg police said late on Thursday a 'Ndrangheta member from San Luca they named as Antonio G. had been arrested in an Italian restaurant in the German city in 1991.
Local police were acting after a tip-off from the Italian authorities who were looking for the man in connection with a suspected murder. He had gone to ground in the Ruhr valley area around Duisburg and been working at various jobs. E-mail to a friend
