A suspected killer has been arrested more than 30 years after the murder of a Lidl store manager outside the shop before it opened in January 1995. Police say the attack happened on 25 January 1995, in Tenisforst, North Rhine-Westphalia. The manager, Sonja K., was in the store stacking goods when unknown attackers stormed in. The woman was tied up and her mouth was taped shut, before she was strangled. Investigators say the attackers then stole several thousand German marks from a safe and fled. So far, the investigation has suggested the crime may have involved multiple people who knew the store and its internal procedures. Police and prosecutors in Krefeld have not released further details. The man has now been arrested as a suspect, with the case still under investigation.
