Berlin: Several people were injured, including a police officer, in a shooting early Tuesday at a Munich subway station, police said.

Munich police said in a tweet that the policewoman's injuries were serious, and that the suspect was in custody.

The shooting occurred during a morning police check at the Unterfoehring subway station, Munich police spokesman Michael Riehlein said.

He had no further details, but Munich's Merkur newspaper reported that witnesses said the suspect took a police officer's pistol and shot her, and also injured others at the scene.

Riehlein said the area has been secured and that there was no danger to the wider public.

'No political or religious motive'

 German police ruled out any political or religious motive in the shooting, saying the attacker acted out of "personal" reasons.

"The sole male perpetrator was motivated by personal reasons. There is no political or religious background here," police spokesman Marcus da Gloria Martins told reporters.
