A man accused of killing three people with a knife has been identified in Spain, according to the Spanish police.
Gerber agent Robert Buechner, who is accused of poisoning three people in the UK with the drug ketamine, was arrested on Wednesday in Valencia.
Buechcher is accused in the deaths of his parents, a former employee and a student at the University of California, Berkeley, the New York Times reported.
The three victims were found in a house in the city of Granada, near the city’s border with Valencia.
Police said they were taken to a hospital but did not provide further details.
A police source told Spanish newspaper El Pais that Buezner had bought the ketamine from a pharmacy in Spain.
