A Beverly Hills police unit was posted outside the couple's $7 million hilltop mansion on the 1100 block of Maytor place. The home invaders shattered a rear glass door to enter the residence around 2:20 a.m. Clarence Avant, 90, was at home at the time, but he wasn't harmed.

The Beverly Hills Police Department will hold a news conference at 12:30 p.m. PT to reveal details about the arrest.

Movie mogul Tyler Perry vowed to use his wealth and "every available resource" to help find the murderer.

He mentioned the couple's daughter, former US Ambassador to the Bahamas, Nicole Avant, in a tweet.

"My heart breaks for Clarence and Nicole and all the Avant family," he tweeted on Thursday. "This world can be so cruel and cold!! I have no idea what kind of sub-human could shoot an 81 year old woman, and in her own home."

He added, "But you can rest assured that every available resource will be used to find whoever is responsible for this awful nightmare. This is tremendously sad."
