A 37-year-old man named Michael Arega has been arrested by the Secret Service after threatening to "kill all white police" via Facebook and traveling to the White House.

The arrest of the man who reportedly lives in Dallas, Texas, was made near the White House on Monday after the Secret Service was tipped off about the threat.

USA TODAY reports:

Police in suburban Montgomery County, Md. sent a be-on-the-lookout notice to the Secret Service for Michael Arega just before 3 p.m. Monday, the Secret Service said.

A little more than an hour later, Secret Service officers spotted Arega on the north side of Pennsylvania Avenue and arrested him "without incident," spokesman Shawn Holtzclaw said.

It was Arega's ex-wife who reportedly tipped off authorities about the threats.

"Now i am going to there to white House make sure kill All white POLICE !!" said one post by Arega.

Another post read: "Put him on jail Donald J Trump mighty name of Jesus Christ."

At around 4 p.m. Eastern time, Arega "checked in" to the White House via Facebook.

The man is currently being held at the Washington Metropolitan Police Department, per the Secret Service.

President Trump was, of course, in Asia at the time of the incident and arrest.
