Federal agents detained a 21-year-old Mexican man — already convicted of assaulting a public servant, deported four times and now charged with assault — last week at the Hidalgo County jail.

U.S. Immigration and Customs Enforcement agents took custody of 21-year-old Yovani Atilano Alcantar on Jan. 5, according to the federal criminal complaint against him.

The federal government last deported Alcantar on Aug. 24 through Laredo.

“The defendant claims to have illegally re-entered the United States on or about November 10, 2015,” by wading the Rio Grande River at or near Hidalgo, Texas,” according to the criminal complaint.

Alcantar was convicted of assault against a public servant and sentenced to seven years probation on Dec. 12, 2013, according to the criminal complaint.

Federal agents found Alcantar at the Hidalgo County jail again last week, when police arrested him on suspicion of assault causing bodily injury-family violence, a Class A misdemeanor.

A woman accused Alcantar of hitting her, according to Hidalgo County court records.

Jailers released him to federal immigration agents.

An attorney representing Alcantar couldn’t be reached for comment on Wednesday.
