An Arizona man who called police to report a possible burglar in his home ended up getting arrested himself in a plot twist after officers discovered a stash of illicit drugs, authorities said.

Responding officers searched the home but found no signs of a break-in, the Phoenix Police Department said on social media. Instead, officers found 6,000 fentanyl pills, 392 grams of meth, $4,685 in cash and a handgun.
