German police have arrested a suspect in a stabbing at Berlin's Holocaust memorial that left a man seriously injured.
Berlin's police department gave no details on the identity of the suspect or his possible motive, and investigations are ongoing.
"Our forces have detained a suspect in the vicinity of the crime scene," city police posted on social media.
Video of the scene showed emergency vehicles and heavily armoured police lined along one side of the memorial site, a vast field of grey concrete pillars.
The victim "was so seriously injured that he had to be taken by the fire brigade to hospital for emergency treatment," police spokesperson Florian Nath said.
Mr Nath said the victim's life was not in danger and he was being prepared for surgery and police were collecting forensic material at the site.
The attack happened on Friday night, local time.
An eyewitness told local broadcaster RBB24 that the two men had appeared to approach each other before the victim was suddenly stabbed. It comes two days before a watershed national election, in which polls suggest a far-right party could come in second place for the first time in nine decades.
The Memorial to the Murdered Jews of Europe is a memorial in Berlin to the 6 million Jews killed in the Holocaust during World War II.
