Terrorism ruled out in Munich knife attack

German police have ruled out terrorism in Munich knife attack in which the attacker wounded four people on Saturday morning.

According to German media, Munich Police Chief Hubertus Andrae ruled out terrorist link and said that the attacker may have been a mental patient.

Earlier, authorities launched a manhunt after the attacker attacked people in the Rosenheimer Platz area of the Bavarian capital, reports The Independent.

Four people are thought to be injured but none sustained life-threatening injuries, The Independent reports quoting the authorities.

Munich police tweeted to give description of the attacker: "a man about 40 years, riding a black bike; wearing grey trousers, green training jacket, backpack+ sleeping mat."

Later, Munich police spokesman Marcus da Gloria Martins told reporters: "We have arrested a person who very strongly resembles the description by witnesses, but we cannot confirm that he is the attacker."

Earlier, the Munich Police said on Twitter that officers were looking for the man "with all available police forces" but that his motive remained unclear.

Munich also witnessed a knife attack last year wherein the attacker later proved to be a mentally disturbed person.
