A man suspected of carrying out a deadly shooting attack in the German city of Munich killed himself, and likely acted alone, police have said.

At least 10 people, including the possible suspect, were killed in Friday’s attack on the Olympia shopping centre, a police spokesman said early on Saturday.

A body found about 1km from the scene was that of the shooter, who appeared to be the sole attacker, officials said.

Earlier on Friday, police had said they were looking for up to three suspects, citing eyewitness accounts.

A massive police operation was launched in the Bavarian capital following the attack, with authorities telling residents to stay indoors. Special forces hunting for suspects were deployed in the streets, while bus, tram and metro services were also suspended.

Al Jazeera’s David Chater, reporting from Munich, said the Bavarian capital had been placed under a state of emergency.

“The city is in a complete state of lockdown,” he said.

There was no information about the possible motive of the attack, in which at least 10 people were wounded.
