GREELEY -- U.S. Immigration and Customs Enforcement special agents arrested three illegal immigrants Wednesday in Greeley.

ICE officials said the suspects include two registered sex offenders and a member of a violent street gang.

Officers from Greeley Police Department assisted with the arrests.

The two sex offenders are a 67-year-old man, and his 33-year-old son, both illegal aliens from Mexico.

They have separate and unrelated convictions based on sex offenses with underage girls.

In 1989, the father was convicted in Los Angeles of sexually assaulting his then 12-year-old daughter. He served three years in prison.

His son was convicted in 2003 in Weld County for sexual assault on his 15-year-old girlfriend when he was 27 years old. He received a five-year deferred sentence.

ICE officials said the third suspect is a 24-year-old man from Mexico they say is an active member of the Norteno street gang. It operates in the Greeley area.

Although he is a U.S. permanent resident, his criminal convictions make him eligible for deportation. He has a felony conviction for “menacing” and two misdemeanor convictions for child abuse and third-degree assault, which are all separate convictions.

The father and son from Mexico were both arrested under ICE’s Operation Predator. Operation Predator is a national ICE initiative that protects children by investigating and presenting for prosecution pedophiles, Internet predators, human traffickers, international sex tourists, and other predatory criminals.

The street gang member was arrested under ICE’s Operation Community Shield. Operation Community Shield is an ongoing nationwide initiative in which ICE agents partner with other federal, state and local law enforcement agencies to address the public safety threat posed by transnational gangs.

Greeley Chief of Police Jerry Gardner, in a statement sent to 7NEWS, said “The simple truth is that we do not want gangsters and known sex offenders in our community, regardless of their citizenship status.”

Last December, Greeley was the site of a major ICE raid at the Swift & Company meat packing plant. Nearly 250 workers were arrested.
