AT least one person has been killed and three others injured after a man went on a stabbing spree in Germany.

Emergency responders launched a major operation after the suspect stormed a utility company and attacked several employees.

German cops said a police investigation is currently underway in Mellrichstadt, where the company is located.

They added: “A police operation is currently underway in Mellrichstadt. Police officers and emergency services are on scene in large numbers.”

It is understood that the suspect is already in police custody.

There is currently no information on the suspect’s motive behind the fatal attack.

German media outlet Bild reports that the office building in Mellrichstadt belonged to Überlandwerke Rhön.

A police spokesman said: “Caring for the injured is our top priority, as is clarifying the exact circumstances of the crime.”

In May, at least 18 people were injured after a woman launched a frenzied stabbing spree at a packed German train station.

The horror unfolded at Hamburg Central Station, one of the country’s busiest transport hubs.

The 39-year-old suspect suddenly pulled out a knife and began randomly stabbing passengers waiting for a train to Munich.

The brutal attack left four people critically injured, six seriously hurt, and eight others with minor wounds, according to emergency services.

The suspect is a German national known to police and has a history of mental illness, having previously spent time in a psychiatric facility.
