Daphne Caruana Galizia's family have filed a criminal complaint saying that an employee at the Office of the Prime Minister stalked the journalist one day before she was murdered. 

The Caruana Galizia family said Neville Gafà "and/or a person known to him" followed the journalist and her husband Peter around Floriana and took photos of them on Sunday 15 October.

The Caruana Galizia family argued that the behaviour qualified as stalking according to Malta's criminal code. They cited Facebook posts and photos Gafà uploaded to his personal profile as evidence.

On the day, Gafà had uploaded two photos of Caruana Galizia, writing "earlier in the afternoon, the Bidnija woman visited a garden in Floriana. It seems she didn't mind mingling with people she would previously have never dreamt being seen alongside. Is solitude kicking in?" 

In the criminal complaint, the Caruana Galizia family cited article 251AA of the criminal code, which lists offences that amount to stalking. 

Gafà made headlines last year after a whistleblower alleged that he pocketed thousands of euros as part of a medical visa racket while working at the Health Ministry.  Gafa denied the accusations.
