German police say a bomb blast that has killed the driver of a car in Berlin may be linked to organized crime gangs.
The explosion occurred on March 15 inside or on a Volkswagen car in Berlin's western district of Charlottenburg. The car's driver was killed in the blast.
Berlin police said there was no indication the explosion was a terrorist attack.
Police spokeswoman Kerstin Ziesmer said investigators were concentrating on the possibility that the explosion might be linked to organized crime.
She said investigators had identified the 43-year-old man who was killed but declined to name him, citing the ongoing investigation.
Berlin has seen a spate of violence linked to biker gangs involved in the drugs trade in recent years.
