A man has died and two women have been injured after a trail of suspected booby traps were left behind by a now-deceased gardener to get revenge on friends and clients.

A German doctor named only as Jorn K, 64, died in an explosion at the entrance to his practice on Friday morning. Police believe the bomb may have been in a package the victim picked up.

Two women, thought to be a mother and daughter, were injured when a booby-trapped piece of firewood caused their wood-burning stove to explode on Sunday.

German police are warning any residents who had a dispute or argument with 59-year-old Bernhard Graumann to be vigilant and to contact them.

In a statement, police said: "The investigators assume for the time being that the culprit placed an explosive device at the front door of the doctor's office.


"Presumably the doctor went to pick up the disguised device from the ground. This caused the object to explode."

Mr Graumann's body was found in his home in Mehlingen, near Kaiserslautern in west Germany, on Friday evening.

Police are investigating whether he poisoned himself, with a post-mortem due on Wednesday.

Investigators searching his house found gunpowder and weapons.

Local media report Mr Grauman was a hunter with a firearms licence and took part in a historical re-enactment club, where he is believed to have used gunpowder.

The doctor was killed in the nearby village of Enkenbach-Alsenborn, while the two unnamed women were injured in Otterberg, around five miles from Mr Graumann's home.

All three victims were known to Mr Graumann, but had fallen out with the landscape gardener.

"Graumann did not have a good relationship with these people," the police said.

"In both cases there had been previous conflicts. The police cannot rule out the possibility that the deceased made preparations to endanger the lives of other people before he died.

"We urge people who had a problematic private or business relationship with Graumann to contact the police urgently."
