Five armed and hooded men got away with an undisclosed amount of money in a hold-up at Alf Mizzi and Sons in Marsa yesterday.
The police said that two of the thieves held up the security guards while their three accomplices entered the offices in Marsa Industrial Estate and made off with the money.
No one was injured.
Duty Magistrate Miriam Hayman appointed a number of court experts to help the inquiry.
