Drake's dad Dennis Graham received some strange phone calls late Wednesday night and the LAPD got involved.

TMZ says the caller was going on and on about Freemasonry and Drake being his son. From there, the cops showed up at Dennis' home and took an annoying phone calls report. 

There's no clue who made the call or what the person's aim was, but police are now investigating the matter.

Dennis, of course, has become a celebrity since Drake shot to fame. But the rapper has accused him of being an absentee father, a charge that Dennis once spoke to him about.

Maybe in the coming days, there will be more info on those strange phone calls.
