Peter Higgs was allegedly dismissed earlier this year after the museum realised that gold jewellery, semiprecious stones and glass dating from the 15th century BC to the 19th century AD were missing, stolen or damaged.
On Wednesday, the museum announced it had put "emergency measures" in place and ordered an independent review of security. The Metropolitan police have launched an investigation.
Higgs, 56, was the museum's curator of Greek collections, Greek sculpture and the Hellenistic period until he was sacked.
His son, Greg, said his father had "not done anything". He told the Telegraph: "He's not happy about it at all. He's lost his job and his reputation and I don't think it was fair. It couldn't have been [him]. I don't think there is even anything missing as far as I'm aware." His father had "lost all faith in the museum", he added.
A spokesperson for the museum said they could not comment because of the police investigation.
On Wednesday, George Osborne, the museum's chair, said the trustees had "taken decisive action to deal with the situation, working with the team at the museum".
