Ten Maltese suspects were arrested Monday over the auto bomb slaying of a prominent investigative journalist, the prime minister and other authorities said, about six weeks after the assassination that shocked Malta and drew European Union pressure to ensure rule of law here.
Muscat said that the eight suspects are all Maltese citizens and were arrested on Monday morning (4 December).
Blogger Caruana Galizia, who was 53 when she was killed in a vehicle bomb attack on October 16, had made repeated and detailed corruption allegations against both Muscat's inner circle and the opposition.
Muscat provided no other concrete information about the arrests or suspects, citing concerns that anything he says could derail any prosecution.
Europol, the European Union's police agency, has sent a team of organized crime experts to help Maltese police investigate the assassination, joining the Federal Bureau of Investigation and Dutch forensic experts.
Caruana Galizia also covered criminal gangs and drug trafficking and was responsible for exposing Malta's links with the so-called Panama Papers document leak.

Following the death, the Maltese government offered a €1m (£890,000) reward for information about Caruana Galizia's murder.
She ran a popular blog in which she relentlessly highlighted cases of alleged high-level corruption, targeting politicians from across party lines.
Ms Caruana Galizia was named by Politico magazine among the 28 Europeans who are "shaping, shaking and stirring" Europe. They were the first known break in a crime that shocked Malta and motivated European Union officials to look into the EU island nation's laws and government. It reads, "We will not be silenced".
Mr Muscat and his wife deny they held such companies. Muscat easily won reelection.
Half an hour before the explosion tore into her vehicle, Galizia wrote on her blog: "There are crooks everywhere you look now". The situation is desperate, ' she wrote in the last blog published on her site days before she was killed. Shortly afterward, he tweeted that two others had been arrested.
