Dec. 4 (UPI) -- Ten people were arrested Monday in connection with the murder of investigative journalist Daphne Caruana Galizia in Malta.
Malta's Prime Minister Joseph Muscat said in a press conference that there was "reasonable suspicion" that the 10 Maltese nationals arrested were involved in the murder.
Muscat said the investigation included the secret services, the police and the Armed Forces of Malta. Police now have 48 hours to question the suspects before deciding whether to release or prosecute them.
The prime minister didn't reveal details about what evidence had been found or the connection of those arrested to the crime.
Galizia's son, Matthew Caruana Galizia, told The Guardian he and his family were kept "in the dark" about the arrests.
The 53-year-old journalist was killed when a car bomb exploded in her vehicle in October, after she filed a police report 15 days earlier to reveal she had been threatened.
Earlier this year, Galizia accused Muscat of wrongdoing, linking him and his wife to the Panama Papers -- some of which detailed financial information including fraud and tax evasion.
However, Muscat said on Monday he had a "personal commitment" to the case.
"As I stated as soon as I learnt about this barbaric act, we will leave no stone unturned to get this case solved," Muscat said. "I am committed to do so more than ever."
