A spokesman of Najib, in a statement last night, said it also contained several documents including the marriage certificate of the former prime minister and Rosmah Mansor.
He said the safe, which was over 20 years old, was forcibly opened by locksmiths as the key had gone missing.
The spokesman said the safe at the Seri Perdana official residence in Putrajaya was, however, part of the house.
“There should not have been any problem opening it,” he added.
The police raids at the house as well as several other locations linked to Najib follow Barisan Nasional’s defeat at the general election last week and calls by the new prime minister, Dr Mahathir Mohamad, for renewed investigations into 1MDB.
