Sources close to the ‘RHOC’ star tell this publication … she’s been having ongoing issues with an ex-boyfriend and called cops Tuesday to report him for possible extortion. We’re told the guy showed up at Liz’s home when police were there and barricaded himself inside.

Our law enforcement sources tell us one person is in custody … but we’re told they’re sweeping the place just to be sure no one else is inside the home.
