Meanwhile, West, 39, performed "Heartless" at the Meadows Music & Arts Festival before he found out about the terrifying heist. "I'm sorry. I'm sorry. Family emergency, I have to stop the show" he told the audience before abruptly leaving the stage
Although a rep for the KUWTK star told PEOPLE following the burglary that "she is badly shaken but physically unharmed," the rapper is taking proactive steps to increase the security surrounding his wife moving forward.
"Kanye is very angry about what happened," a source tells PEOPLE. "He always loved the apartment and has had it for years. He will obviously be changing the security details from now on. He feels crappy about what Kim had to go through."
Kardashian West, 35, left France on Monday just hours after the incident and returned to New York City, where she reunited with West surrounded by throng of security personnel at her Manhattan apartment.
And though Kardashian West's bodyguard Pascal Duvier was absent during the life-threatening incident because he was keeping watch over sisters Kourtney Kardashian andKendall Jenner, a second source close to the Kardashian family tells PEOPLE it's unlikely he will be blamed.
"I cannot even remotely imagine Kim or the family is blaming Pascal. He is not only Kim's security but also security for the family. He's incredibly professional and takes his job with the family VERY seriously," the second source tells PEOPLE. "Kim herself probably presumed things were safe in her room when Pascal was out with the group."
