Second man arrested over Mac Miller’s death

Another man has been arrested in connection with Mac Miller’s fatal overdose.

36-year-old Lake Havasu City resident Ryan Reavis is in custody … this after the FBI and DEA targeted him over Mac’s death. The law enforcement agencies obtained a search warrant for Reavis’ home, and what they found led to his arrest.

According to investigators, drugs were found — including prescription-only pills and marijuana.

Cops say they also confiscated firearms, including a 9mm pistol and two shotguns, a homemade firearm suppressor and an arsenal of ammo.

Perhaps most important … police found a physician’s prescription pad.

Reavis was arrested and booked on fraud, drug and gun charges on $50,000 bail.

You will recall … Mac’s alleged dealer, Cameron James Pettit, was arrested a few weeks ago for allegedly supplying Mac with deadly counterfeit oxy pills … which cops say led to his death.

In the charging docs, prosecutors said Pettit worked with two women, who police say also played a role in supplying Mac with drugs 2 days before he died.
