Feb. 24 (UPI) -- Local and federal authorities are saying they thwarted a mass casualty attack Monday morning with the arrest of a 21-year-old Texas man accused of making terrorist threats against police officers.

Seth "Andrea" Gregori was arrested shortly after 9 a.m. CST Monday, the Corpus Christi Police Department said in a statement.

Little is publicly known about the alleged plot, but the FBI's Houston field office said Gregori had planned "an attack on police similar to the 2016 Dallas ambush" when Micah Xavier Johnson killed five police officers and injured nine others, as well as two civilians, in a mass shooting.

"FBI Corpus Christi and local partners have thwarted another mass casualty attack!" FBI Houston said on X.

According to the Corpus Christi Police Department, the FBI was notified of "terroristic threats" Gregori had made, investigated the alleged crime and secured a warrant for his arrest.

"The Corpus Christi Police Department greatly appreciates the assistance of our local, state and federal partners in helping to keep our community safe," the police department said.

"Their support is vital to helping us accomplish our mission to reduce crime, the fear of crime and enhance public safety."

According to the FBI, Gregori was arrested on state charges filed by the Nueces County District Attorney's Office.
