The theft was only discovered on Sunday afternoon at the Aguilar household on Avery Street, Barangay North Fairview.
Fairview police commander Superintendent Virgilio Fabian said the money was last seen inside a vault at the master bedroom.
Aguilar told police that he last saw the money when he opened the vault at around 3 p.m. of Aug. 20.
Fabian noted that only the money was missing, adding that a gun left near the vault was untouched.
Curiously, the vault was undamaged and its combination lock and key hole intact.
The police official said that there were no signs of forced entry at all.
“Mr. Aguilar believes it is an inside job,” Fabian said, adding that only someone with access to the vault aside from the singer can open it.
The police official said Aguilar knew the culprit but did not divulge it to police.
