Immigration and Customs Enforcement agents in Houston arrested a Vietnamese national who had been convicted of attempted capital murder of a police officer and had avoided deportation since 2011, according to federal officials.

The arrest represents one of two recent cases involving foreign nationals charged with violent crimes in Texas. In a separate incident, authorities have accused a Mexican national who was previously deported of killing two women by strangulation and shooting two other women who survived the attacks.

The Vietnamese national's case involved a conviction for attempting to murder a law enforcement officer, though specific details about the original incident were not immediately available. Federal immigration authorities said the individual had successfully evaded deportation efforts for more than a decade.

The Mexican national faces charges related to what authorities describe as a series of violent attacks against women in Texas. Two victims died from strangulation, while two others survived gunshot wounds, according to law enforcement officials.

Both cases highlight ongoing challenges faced by immigration enforcement agencies in locating and deporting individuals with criminal convictions. The timing of the arrests and the announcement of charges were not specified by federal authorities.
