A man has been arrested in southern Germany in connection with the murder of a woman whose body was found stuffed in a suitcase in the Maas river last Friday.

The man, who is 53 and comes from Aachen, is the dead woman’s partner, police said in a statement.

The case was the subject of a Dutch television crime show on Tuesday night, which generated several dozen tips. The man was arrested later that evening by Aachen police, who had set up a team to investigate the murder on Sunday, the police statement said.

Two eyewitnesses saw a man throwing a large suitcase into the river last Tuesday night.
