The Friday incident, which critically injured a man, came just a few months after a Ukrainian refugee riding one of the city's trains was killed in a violent knife attack.
Solarzano has been charged with attempted first-degree murder, assault with a deadly weapon and other crimes stemming from the Friday afternoon attack.
Solarzano was being held in jail Saturday without bond. A magistrate judge said in a court filing that the suspect was in the U.S. illegally and had previously been deported.
President Trump commented Saturday about the latest stabbing on his Truth Social site. “Another stabbing by an Illegal Migrant in Charlotte, North Carolina. What’s going on in Charlotte? Democrats are destroying it, like everything else, piece by piece!!! President DJT”
Saturday's violence came less than four months after a 23-year-old woman from Ukraine was killed on a Charlotte commuter train in an apparently random assault captured on video. The victim, Iryna Zarutska, had been living in a bomb shelter in Ukraine before coming to to the U.S. to escape the war, her relatives said.
A suspect, Decarlos Brown Jr., has been charged first-degree murder for Zarutska's killing in a North Carolina state court, and was also indicted in federal court on a charge of causing death on a mass transportation system.
Brown has a long record of other violent offences.
The death of the Ukrainian woman sparked anger among allies of President Donald Trump and figures in his Make America Great Again movement. Many pointed to the case as evidence that federal intervention was needed because leaders of large cities and state governors, most of them Democrats, are failing to protect their residents from crime and rampant illegal immigration.
