An Italian man suspected of murdering six people was arrested in Amsterdam on Thursday evening. The shoot-out is believed to have been a revenge attack between mafia families.

The man is wanted for killing six people during a shoot-out in the German town of Duisburg in August 2007, reports the Parool.
Several people have already been arrested for the murders, including the Italian man’s brother-in-law, says the paper.
The information came from the Duisburg police, but Amsterdam police would not comment, says the Parool.
