Denise Richards‘ estranged husband Aaron Phypers was arrested outside of court Friday … and now we have his official charges.

According to documents obtained by TMZ, Aaron was charged with 2 felony counts of injuring a spouse, and 2 felony counts of dissuading a witness by force or threat, with his total bail set at $200,000.

Michael Finley, Aaron’s lawyer, previously told TMZ … Aaron was not aware of the warrant … and Finley accuses Denise and her legal team of “setting him up” at Friday’s proceedings.

The arrest followed a contentious court hearing where Denise and Aaron were fighting over a permanent restraining order she wanted against him.

The hearing got heated when Aaron’s mother testified she witnessed Denise throw a can opener at Aaron. She also denied her son ever abused or threatened Denise … something Denise has repeatedly claimed.

Aaron swiftly posted bond Friday night.

As you know, the pair is in the midst of a nasty divorce battle that kicked off when Aaron filed to end the marriage in July … and it’s been a whirlwind ever since.
