A US immigration agent has been charged with felony for allegedly hitting a man with a vehicle earlier this month in Texas, a prosecutor announced.

The prosecutor said US Immigration and Customs Enforcement (ICE) officer Mario Alberto Morales was indicted by a grand jury on a charge of aggravated assault with a deadly weapon.

Morales is accused of running over a Mexican national who was living in the US without legal documentation, leaving him with multiple leg fractures and a hip injury.

An ICE spokesperson dismissed the indictment as “nothing more than a political stunt” and described the allegations as “reckless and false”.

The indictment comes amid the Trump administration’s crackdown on illegal immigration and a series of violent incidents involving federal agents that have resulted in injuries and deaths.

If convicted, Morales faces between two to 20 years in prison for the second-degree felony, according to Harris County District Attorney Sean Teare.

Teare said Morales pursued a vehicle driven by Miguel Parra-Hernandez, a 48-year-old Mexican national who has lived in Texas for more than 30 years without legal documentation, on the morning of 10 October.

Parra-Hernandez and another occupant fled the vehicle on foot before Morales “aggressively steered his vehicle” into the Mexican national, Teare said at a news conference in Houston on Friday.

He said Parra-Hernandez had no criminal record and was not subject to a deportation order.

“Not only did he hit Mr Hernandez, he ran over both of his legs, leaving him seriously injured and hospitalised to this day,” Teare said.

Morales then called 911 to report that Parra-Hernandez had hit his car.

Teare said that ICE was allegedly pursuing a man named Jose Mendoza-Cervantes, a Mexican national and undocumented immigrant, who has apparently been dead for nine years.
