Former Economic Crimes Unit superintendent Ray Aquilina has reportedly been arrested in connection with an investigation into leaks of information about the Daphne Caruana Galizia murder.

The Times of Malta reported that Aquilina was taken in for police questioning on Wednesday with a number of others who are believed to have played a part in giving out secret information to those allegedly involved in the 2017 murder.

The middleman in the murder Melvin Theuma has already testified in court that he had details about the investigation and, in particular, about where police raids would take place.

Aquilina is said to be the person who allegedly supplied the information to Theuma. 

He is no longer a police officer.

One of the hitmen Vincent Muscat also testified that he and the other two men accused of killing Caruana Galizia – Alfred and George Degiorgio – knew when they would be arrested almost two weeks in advance.

Aquilina is being interrogated at the police’s Economic Crimes Unit headquarters in Hamrun.

An inquiry into all the leaks on the murder investigation is still ongoing.

Aquilina had testified at length in the public inquiry into Caruana Galizia’s murder, speaking about his work within the Economic Crimes Unit at the time and about what the police was doing on money laundering allegations which Daphne had reported on while she was still alive.
